P0000ERRORTier 2 — Caution✅ HIGH confidenceplpgsql_error
What this means
A generic PL/pgSQL error that does not fall into a more specific PL/pgSQL error category. Used as the catch-all SQLSTATE for PL/pgSQL runtime errors.
Why it happens
- 1PL/pgSQL RAISE with SQLSTATE P0000 (or no SQLSTATE specified)
- 2Unclassified runtime error in a PL/pgSQL function
- 3Exception block catches and re-raises with P0000
How to reproduce
Execution of a PL/pgSQL function or procedure that encounters a generic error
DO $ BEGIN RAISE EXCEPTION USING ERRCODE = 'P0000', MESSAGE = 'generic plpgsql error'; END $;Fix 1: Use a more specific SQLSTATE or error message
You control the PL/pgSQL code raising this error
RAISE EXCEPTION 'More descriptive error message' USING ERRCODE = '22023';Why this works
Using a specific SQLSTATE helps callers catch and handle specific error types
What not to do
Do not use P0000 for application errors you want callers to handle specifically
Why it's wrong: P0000 is a catch-all; callers cannot distinguish it from other P0000 errors
