Thread: pg_dump: schema with OID 2200 does not exist

Hi All,

I'm running into a weird issue with PostgreSQL 9.1.3 and PostGIS 2.0
when trying to dump a table - no matter what table I try to dump in this
database, I find that I get the same error, as evidenced below (scroll
down for relevant data/error output.)

Any ideas as to what might be the root cause of it ?

The error, and some output from relevant queries is below.  In this
case, those things that are "supposed" to live in 2200 seem to be some
PostGIS related tables and views - which were moved after installation
(IIRC) using the alter extension statement (moved into the PostGIS
schema.)  Though the original public schema still exists...

I've got another database (also with postgis 2.0 installed) where it's
not possible for some reason to dump the postgis.spatial_ref_sys table
(dumps return nothing, though I can query the table directly.)

Thanks

Chander

2200 would normally be the "public" schema.  Since you show it having a
different OID, I suppose you dropped and recreated it at some point.
The question is, how did you manage to do that if there were still
objects in it?  Can you reproduce the sequence of events that led to
this state of affairs?  Since you mention moving things with ALTER
EXTENSION, I wonder if there could be a bug in that, but this report
is way too vague for somebody else to investigate.

            regards, tom lane

The answer was in the email to which you responded.  Did you have
