Query goal: | Find user user-defined routines that produce a temporary table |
Notes about the query: | Refers to the column pg_proc.prokind and thus works starting from PostgreSQL 11. The query does not consider the routines that are a part of an extension. In the returned body of routine the query replaces each newline character with the line break (br) tag for the better readability in case the query result is displayed in a web browser. |
Query type: | General (Overview of some aspect of the database.) |
Query license: | MIT License |
Fixing suggestion: | Consider using a subquery instead of putting intermediate results into a temporary table. |
Data source: | INFORMATION_SCHEMA+system catalog |
