Basic PostgreSQL client applications for Windows. It includes native win32 SQL terminal and backup tools, psql and pg_dump with gzip, for execution of SQL scripts and access to PostgreSQL servers remotely by administrators and end users.
DO NOT use this client with any modern Postgres version. Please use the official psql.exe that comes with the supported Windows binaries available from the Postgres homepage. Again: DO NOT use this anymore. It is outdated and only works for a Postgres version that has not been supported for several years now.
