Attached patch will add a version() function to Postges, e.g. template1=> select version(); version ------------------------------------------------------------ PostgreSQL 6.3.2 on i586-pc-linux-gnu, compiled by gcc 2.8.1 (1 row)
The utils directory contains components that are used by multiple subsystems in the Postgres source tree. We don't want subsystems reaching into other subsystems' directories and messing with the modularity of the system, so we gather any cross-subsystem utilities here. In particular, programs that form an interface between subsystems go here.
