plpgsql_error (SQLSTATE P0000) is a generic runtime error raised inside a PL/pgSQL function when no more specific SQLSTATE is supplied.
plpgsql_error (SQLSTATE P0000) is a catch-all runtime error thrown inside a PL/pgSQL function when an EXCEPTION block re-raises or a RAISE command omits a SQLSTATE code. Add a specific RAISE EXCEPTION SQLSTATE or handle the underlying issue to resolve the error.
plpgsql_error
plpgsql_error is PostgreSQL’s generic SQLSTATE P0000 raised from inside PL/pgSQL code.
The error surfaces when a RAISE command omits an explicit SQLSTATE or when an EXCEPTION block rethrows an unhandled condition. Because P0000 is non-specific, debugging requires inspecting the function body and the underlying statement that failed.
Omitting SQLSTATE in RAISE EXCEPTION causes PostgreSQL to default to P0000.
The database cannot classify the error further, so it labels it plpgsql_error.
Re-raising an exception without changing SQLSTATE inside a BEGIN … EXCEPTION block will also propagate as P0000 if the original code path lacked a defined code.
Syntax bugs, constraint violations, or NULL value errors inside the function may bubble up as plpgsql_error when captured generically.
Locate the exact line that triggers the exception by setting client_min_messages = debug and using RAISE NOTICE statements for tracing.
Add an explicit SQLSTATE to every RAISE EXCEPTION such as RAISE EXCEPTION USING ERRCODE = '22012' to convey divide-by-zero errors clearly.
Restructure EXCEPTION blocks so that they handle specific conditions or re-raise with a clarified SQLSTATE and message.
NULL references: Accessing record.field when record is NULL throws a plpgsql_error.
Check for NULL before access.
Unique constraint violations: An INSERT inside a function fails and the EXCEPTION block re-raises blindly. Capture unique_violation and handle or re-raise with ERRCODE 23505.
Dynamic SQL failures: EXECUTE format(...) errors propagate as P0000.
Wrap EXECUTE in its own EXCEPTION block and log the generated SQL.
Add explicit SQLSTATE codes in every RAISE EXCEPTION call.
Handle specific exceptions like NO_DATA_FOUND, TOO_MANY_ROWS, unique_violation, then log or re-raise with context.
Use Galaxy’s inline linting to spot unqualified RAISE statements and missing EXCEPTION branches before deployment.
P0001 RAISE_EXCEPTION - Triggered by RAISE EXCEPTION with default SQLSTATE.
P0002 NO_DATA_FOUND - SELECT INTO found zero rows.
Add EXISTS check or RETURN NULL.
P0003 TOO_MANY_ROWS - SELECT INTO returned more than one row. Add LIMIT 1 or DISTINCT ON.
.
When PL/pgSQL cannot map an error to a predefined SQLSTATE class, it assigns the generic plpgsql_error code.
No. It masks the real problem. Always locate and either handle or re-raise with a precise SQLSTATE.
Enable log_min_messages = debug, sprinkle RAISE NOTICE calls, or run the function in Galaxy’s step-through debugger.
Galaxy flags unqualified RAISE commands during review and suggests explicit SQLSTATE codes, reducing the chance of plpgsql_error reaching production.
