A former system function implemented as an alias for factorial()
This entry relates to a PostgreSQL feature which is deprecated and may be desupported in future releases.

numeric_fac() is a former system function which was implemented as an alias for factorial().

numeric_fac() was added in PostgreSQL 8.0 and removed in PostgreSQL 14.


numeric_fac ( bigint ) → numeric

numeric_fac() was added as an undocumented alias for factorial(), presumably as it matches the internal function name providing this functionality.
