is this maybe related to postgresql config ??
PostgreSQL 13.14 (Ubuntu 13.14-1.pgdg22.04+1) on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0, 64-bit

[SamirTalwar]

@sasog23: Is it perhaps a latency issue?

How long does it take to run SELECT 1 from the "Run SQL" tab of the Hasura Console?

[sasog23]

nope, it's ok
i've tested this query in pgadmin, and it takes 8+ seconds
if i remove "AND ((pgn.nspname='servicedesk'))" and test it, it takes <1s

[SamirTalwar]

@sasog23, would you mind getting us an execution plan?

You can run the same query in pgAdmin, but prefix it with EXPLAIN, and then paste the results here. (Please redact any information you need to.)

We're seeing quite a different analysis here compared to local testing. It could be that indices are misbehaving somehow.

I suggest running VACUUM ANALYZE on the database and seeing if this helps.
