Description: Debian version number type for PostgreSQL
Debian version numbers, used to version Debian binary and source
packages, have a defined format, including specifications for how
versions should be compared in order to sort them. This package
implements a "debversion" type to represent Debian version numbers
within the PostgreSQL database. This also includes operators for
version comparison and index operator classes for creating indexes on
the debversion type.
.
Version comparison uses the algorithm used by the Debian package
manager, dpkg, using the implementation from libapt-pkg. This means
that columns in tables using the debversion type may be sorted and
compared correctly using the same logic as "dpkg --compare-versions".
It is also possible to create indexes on these columns.
.
postgresql-debversion implements the following features:
.
* The "debversion" type (internally derived from the "text" type)
* A full set of operators for version comparison (< <= = <> >= >)
including commutator and negator optimisation hints
* Operator classes for btree and hash indexes
* The aggregate functions min() and max()
