Обсуждение: BLOB problem
Hi,
I've encountered a problem with a PostgreSQL database. I made a image management system which stores images in a database from a PHP script. I upload te file using pg_lo_import() (PHP function). Everything works fine, fast, and I was really glad with it, till I found out that my database is rapadly growing. With only 20 images the database has a size of 65 MB !!!
Does anybody know where this come from ? I know I don't give a lot of information, if you want more, ask for it. But I don't want to send unreadable posts ;-)
Grtz

Are you running VACUUM regularly? You might want to do a VACUUM FULL and see if the size goes down again. The other possibility is that you're not dropping large objects when they're superseded by new ones. If you never call lo_unlink() in your code that's probably what's happening. -Doug
