I tried to CREATE EXTENSION vacuumlo, but it fails with the following message:
"/usr/pgsql-9.4/share/extension/vacuumlo.control": no such file or directory.
I can see other
.control files in that directory, and I was able to CREATE EXTENSION pgstattuple from it, but the vacuumlo files are indeed missing.
This is a VERY old server, and neither I nor others at the client have any PG experience (those that configured the server and apps are long gone).
I was told to use this tool to determine pg_largeobject bloat on this thread:
How can I compile/use vacuumlo if the code is not in that directory?
