segfault using etcd_fdw

[pashagolub]

Today I had segfault probably due to parallel queries accessing etcd_fdw:

2026-02-13 13:14:27.550 UTC [1] LOG:  server process (PID 1242) was terminated by signal 11: Segmentation fault
2026-02-13 13:14:27.550 UTC [1] DETAIL:  Failed process was running: CALL timetable.f_control_importers();

I still don't have much data to reproduce, so I'll just leave it here in case I'll hit it again.

Hi, has this happened again since you created this issue?
