We are doing application/database migration compatible with postgresql on cloud, DR/replication also in plan

at present I feel need of configurable multi-table storage instead of pg_largeobject only

Thanks

Some time ago I had to setup a replicated file system between multiple linux servers. I tried everything I could based on postgres, including large objects, but everything was significantly slower than a regular filesystem.

My conclussion: postgres is not suitable for storing large files efficiently.

Do you need that for replication, or just for file storage?

all media files are stored in database with size varies from 1MB - 5GB

based on media file types and user-group we storing in different tables, but PostgreSQL store OID/Large-object in single table (pg_largeobject), 90% of database size is with table pg_largeobject

due to size limitation BYTEA was not considered

Hi

pg_largeobject is creating performance issues as it grow due to single point storage(for all tables)

is there any alternate apart from bytea ?

like configuration large-object-table at table-column level and oid PK(primary key) stored at pg_largeobject


I would as soon use a NFS file store for larger files like images, audio, videos, or whatever.   use SQL for the relational metadata.

just sayin'....
