pg_proc

A system table which stores information about functions, procedures, aggregate functions, and window functions

pg_proc is a system catalogue table which stores information about functions, procedures (from PostgreSQL 11), aggregate functions, and window functions.

pg_proc has always been present in PostgreSQL.

Source code

Between PostgreSQL 8.4 (commit 039dfbfd) and PostgreSQL 11 (commit cefa3871), an additional source file src/include/catalog/pg_proc_fn.h existed to enable catalogue definitions to be included by frontend code.
