Re: Picture with Postgres and Delphi

Ahh ok, thats in the programmers docs. Ok, so I'm guessing that really large
object support (BLOBs) are depreciated in favor of using the "bytea" or "text"
types, yes? I would this this to be true since your "object" is contain within
a single record and non spanned because of row limit (i.e. before TOAST).

So then the "large object" function in the Pg.pm are not what I'm looking for.
I'm back to square one- How does one actually insert a file into a table using
Pg.pm or more importantly psql? I'm more concerned about doing this on the
system first since that is where I would be scripting the initial load of all
the images- something like that should not be done via a web client.
