Parser Fixes & Improvements

Added

• parser: surface variadic token in Arg AST node (#1201)

Fixed

• parser: fix gaps with cte search/cycle, grant, vacuum, at local, & more (#1198, #1199, #1200)
• parser: fix collate parsing in create table + more (#1197)

Fix False Positive with Require Schema Rule & Github Actions Output Clobbering

Added

• fmt: support comments in group by (#1194)

Fixed

• linter: fix github actions output clobbering json/gcc (#1192)

• linter: fix require table schema false positive on temp tables (#1191)

  Previously this would error:

Fix Precommit Install & IDE Improvements

Fixed

• ci: fix precommit install by declaring optional dependencies (#1180)

• ide: fix select * w/ create view & more (#1184)

  The following now works correctly:

  create table t(a int);
  --             ^ dest
  create view v as table t;
  select a$0 from v;
  --     ^ src

• ide: treat select into like create table as (#1183)

  create table t(a bigint);
  --             ^ dest
  select * into u from t;
  select a from u;
  --     ^ src

• ide: fix column resolution with cte & shadowing (#1182)

  with outer_cte as (select 1 c)
  --                          ^ dest
  select * from (
    with inner_cte as (select 2 d)
    select c from outer_cte
  --       ^ src
  ) s;

• ide: fix aliases not hiding original name (#1181)

  update t as u set a = t.a;
  --                    ^ error

• ide: fix cte & alias resolution (#1179)

    with
      a as (select * from b),
  --                      ^ src doesn't resolve
      b as (select 1 x)
    select * from a;

• ide: don't resolve trailing FromItems in a lateral subquery (#1177)

  with
    d as (select 1 id, 2 amount),
    c as (select 2 id)
  select r.amount
  from
    d,
    lateral (
      select d.amount
      from d
      where d.id = c.id
      --           ^ src doesn't resolve
      limit 1
    ) r,
    c;

Parser Improvements & Fixes + Error Docs Hyperlinks

Added

• parser: validation for default usages (#1175)

  -- ok
  insert into t values (default);

  -- err
  select default;

• linter: setup hyperlinks for rule names in terminal (#1174)

  If your terminal supports it, then clicking on the rule name will navigate
  you to the docs.

Fixed

• fmt: upgrade tiny_pretty to latest (#1173)

  We no longer wrap statements unless necessary.

• parser: fix parsing period column (#1172)

  previously we'd error on:

  create table t (
    symbol text,
    period text,
    year int,
    quarter int,
    primary key (symbol, period, year, quarter)
  );

Improved Parser Validation for Strings + Updated Install Method

Added

• parser: validation for bit, byte, and escape string types (#1132)

  select b'01' '10';
  select x'0F' '10';
  select e'foo' 'bar';

  now gives:

  error[syntax-error]: Expected new line or comma between string literals
    ╭▸ stdin:1:13
    │
  1 │ select b'01' '10';
    ╰╴            ━

• parser: validation for escape sequences (#1125, #1123, #1122, #1128, #1129)

  select U&'wrong: !061' UESCAPE '!';
  select U&"wrong: \06" UESCAPE '\';

  now gives:

  error[syntax-error]: Unicode escape requires 4 hex digits: !XXXX
    ╭▸ stdin:1:20

    ╰╴                   ━━━

Changed

• ci: update npm based install method (#1133)

  Instead of fetching the binary via an install script we use an optional
  peer dependency, mirroring ESBuild and Sentry.

Fixed

• cli: fix missing binary exit code (#1130)

  Before if the install script didn't run the NPM JS shim would exit without
  erroring. Thanks @nwalters512!

• parser: parsing unicode escape idents in cast position (#1127)

  select 2::U&"!0069!006E!0074!0038" UESCAPE '!' from t;

  now parses without error

File Level Disable Comment For `assume_in_transaction`

v2.51.0 - 2026-05-06

Added

• linter: add file-level override to disable assume_in_transaction (#996). Thanks @reteps!

  When using assume-in-transaction, you can disable it on a per file basis using a comment:

  -- squawk-disable-assume-in-transaction

• syntax: add validation for select into (#1116)

  Warn about invalid usages, such as:

  • select 4 a union select 5 a into t;
  • with t as (select 1 a into t) select * from t;
  • select * from t where a in (select 1 a into t);

  and more!

• parser: add empty statement to ast (#1111)

  ;
  ;
  ;

  now gives:

  [email protected]
    [email protected]
      [email protected] ";"
    [email protected] "\n"
    [email protected]
      [email protected] ";"
    [email protected] "\n"
    [email protected]
      [email protected] ";"
  

• ide: code actions create table as <-> select into + parser fix (#1113)

  Create table and select into are roughly interchangable, so this code action
  supports switching between.

• ide: show comments for types and columns (#1110)

• ide: hover infer more types for columns (#1109, #1108)

Changed

• parser: cleanup insert & create rule ast grammar to be more strict (#1112)

Fixed

• vscode: fix text mate grammar for multiple stmts on a line (#1115)
• ide: fix infer column name w/ column aliases and goto def (#1118)
• ide: fix output column alias resolution in group by / order by (#1117)
• ide: fix inherit/like resolution + cte fixes (#1107)

New Rules: Prefer Repack, Identifier Too Long, Require Concurrent Reindex, Require Concurrent Partition Detach + A Lexer Fix

Added

• linter: new rule: prefer-repack (#1105)

  repack isn't out yet, coming in PG19, but when it's out:

  -- instead of
  cluster foo;
  -- or
  vacuum full foo;
  -- use
  repack (concurrently) foo;

• linter: new rule: require-concurrent-reindex (#1104)

  -- instead of
  reindex table foo;
  -- use
  reindex table concurrently foo;

• linter: new rule: require-concurrent-partition-detach (#1103)

  -- instead of
  alter table t detach partition p;
  -- use
  alter table t detach partition p concurrently;

• linter: new rule: identifier-too-long (#1102)

  Postgres truncates identifiers that are too long, we now warn about this.

  create table table_very_long_very_long_very_long_very_long_very_long_very_long (c bigint);

  warning[identifier-too-long]: `table_very_long_very_long_very_long_very_long_very_long_very_long` is too long and will be truncated to 63 bytes.

  Thanks @subnix for coming up with this idea!

• linter: parallel file checking (#1099)

  We now check files in parallel using rayon, which gives a nice speed up of
  22-55%.

• lexer/ide: fix lexing of non-ascii + fix case folding in goto def (#1101)

  Previously we case folding all of the characters in our unquoted identifiers
  including unicode. This differed from Postgres behavior which only folded ascii.

  Now we correctly error instead of resolving in the following:

  with t as (select 1 Äpfel)
  select äpfel from t;
  --     ^ goto def no longer resolves

  Additionally fixed a bug in the lexer where we weren't lexing unicode identifiers.

  For example, the following now lexes:

  with t as (select 1 🦀)
  select 🦀 from t;
