A repository of custom PostgreSQL functions and extensions.
A plperlu function returning the creation date of a database,
based on the creation time of the database directory
under $PGATA/base.
A simple plpgsql function that takes two table names (through the
regclass type), builds a query comparing their contents, runs
it, and returns a set of diff-like results with the rows that differ.
It does not require a primary key on tables to compare.
Return a CURSOR pointing to pivoted results of a query passed as the
1st parameter, with sorted headers passed as a query as the 2nd
parameter.
See https://postgresql.verite.pro/blog/2018/06/19/crosstab-pivot.html for
a lot of context about this function.
A plpgsql function that finds occurrences of a string or more
generally perform any kind of text-based matching in all or some of the
tables of an entire database.
It returns the table, column name, ctid and column's value of the rows
that match.
The search can be limited to an array of tables and/or of
schemas. Progress is optionally reported by emitting raise info
messages.
C functions that return the number of bits set to 1 in a bytea, int
or bigint value. The bytea variant is available as a built-in function
(named bit_count) since PostgreSQL 14.
A plpgsql function that returns the size of a given large object.
A plperlu function that returns the digest (hash output) of a large object for any hash supported by perl's Digest module.
A simple function to parse name=value settings.
Replace strings by other strings within a larger text, with Perl s// operator, in a single pass. Each string in the first array is replaced by the element at the same index in the second array.
Truncate an UTF-8 string to a given number of bytes, respecting the constraint that any multibyte sequence at the end must be complete.
A text search dictionary to filter out tokens longer than a given length.
psqlrc declarations, companion scripts, tricks for the psql command-line interpreter.
