Обсуждение: Dangling large objects

    I'm in a bit of a bind here.  I wrote some code in our abstraction
layer to automatically unlink large objects when the row referencing
them is deleted (I know that they are only referenced once).  However,
I neglected to include them in a transaction, so I'm pretty sure that
those unlinks never happened.

    Is there any simple way for me to get a list of all large objects
in a database, so I can see if there are actually rows referring to them
and delete the ones that were not unlinked earlier?

Look at the vacuum_lo contrib module.

BTW, I believe lo_unlink doesn't need to be in a transaction block,
only lo_open/read/write/close do.

Dangling large objects?  I thought this was a family list. :-)
