only remnant of this failed experiment is that the server will take SET AUTOCOMMIT TO ON. Still TODO: provide some client-side autocommit logic in libpq. |

$Header: /cvsroot/pgsql/contrib/vacuumlo/Attic/README.vacuumlo,v 1.2 2000/11/21 17:54:21 tgl Exp $ This is a simple utility that will remove any orphaned large objects out of a PostgreSQL database. An orphaned LO is considered to be any LO whose OID does not appear in any OID data column of the database. Compiling -------- Simply run make. A single executable "vacuumlo" is created. Usage ----- vacuumlo [-v] database [db2 ... dbn] The -v flag outputs some progress messages to stdout. Method ------ First, it builds a temporary table which contains all of the oid's of the large objects in that database. It then scans through all columns in the database that are of type 'oid', and removes any matching entries from the temporary table. The remaining entries in the temp table identify orphaned LOs. These are removed. Notes ----- I decided to place this in contrib as it needs further testing, but hopefully, this (or a variant of it) would make it into the backend as a "vacuum lo" command in a later release.
