Error 22023 appears when a GUC or function argument receives a value that is outside the allowed range or data type constraints.
PostgreSQL Error 22023 (invalid_parameter_value) occurs when a parameter or setting is assigned a value PostgreSQL cannot validate. Adjust the value to an accepted type or range to resolve the error.
PostgreSQL Error 22023
Error 22023 signals that PostgreSQL rejected a supplied parameter value because it is out of range, misspelled, or of the wrong type.<\/p>
The failure can happen in configuration commands, function calls, or SQL statements that pass arguments to server settings. Prompt correction is essential because the statement halts and any transaction may roll back.<\/p>
PostgreSQL validates every parameter against an allowed set of values.
Passing an unsupported keyword, negative number where only positives apply, or an improperly quoted string triggers error 22023.<\/p>
Many server configuration variables (GUCs) such as work_mem, search_path, or application_name have strict formats. Functions like set_config and pg_sleep also enforce type rules, leading to this exception when violated.<\/p>
Identify the exact parameter mentioned in the server log or client message. Consult pg_settings to view accepted ranges or enumerate allowed enums.
Correct the value and rerun the statement.<\/p>
If the problem appears during ALTER SYSTEM or SET commands, edit postgresql.conf or pg_parameter_status entries, reload the server, and verify with SHOW parameter_name.<\/p>
Setting work_mem to "2GB" instead of "2GB" (missing unit) causes 22023; fix by adding an explicit unit. Supplying an array to a function that expects text also triggers the error; cast the value properly.<\/p>
In CI scripts, invalid search_path strings often surface.
Validate by calling SELECT current_setting('search_path'); after applying changes.<\/p>
Always query pg_settings before changing configuration. Use CHECK constraints in functions to validate incoming arguments. Implement automated tests that run SHOW commands in migrations.<\/p>
Galaxy’s SQL editor flags invalid GUC values inline and provides AI suggestions, reducing the chance of deploying faulty parameters.<\/p>
Error 22022 (indicator_overflow) occurs when a pointer exceeds bounds; verify data types.
Error 42601 (syntax_error) surfaces when the SQL is malformed; ensure proper grammar.<\/p>
Error 42804 (datatype_mismatch) arises when cast rules fail; adjust casting. Each requires specific validation steps but shares the theme of guarding input.<\/p>.
