Antananarivo, Madagascar - April 19, 2025 ## PostgreSQL large object to bytea converter
First release v1.0 of oid2bytea tool has been published. oid2bytea is a program used to convert large objects columns in a PostgreSQL database into bytea. oid2bytea will automatically detect the oid columns and process to their bytea transformation automatically; parallel processing can be used to accelerate the migration. Of course you can also choose which tables need to be processed or filter on a schema. Two migration modes are supported: `local` and `remote`. In `local` mode the large objects data stored in the `pg_largeobject` table will be moved into a newly created bytea column with the same name and the old oid column will be removed. In `remote` mode oid2bytea will migrate the local oid columns to a remote database with the same structure except that the oid columns have been replaced by bytea columns of the same names. ## Links & Credits oid2bytea is an open project under the PostgreSQL license maintained by [HexaCluster Corp](https://hexacluster.ai).
