Wiki / Functions

Splits the string at occurrences of delimiter and forms the resulting fields into a text array. If delimiter is NULL, each character in the string will become a separate element in the array. If delimiter is an empty string, then the string is treated as a single field. If null_string is supplied and is not NULL, fields matching that string are replaced by NULL. See also array_to_string.

English manual coverage begins with PostgreSQL 7.1. Source history and runtime observations have their own recorded version boundaries.
