Re: Problem with extension

Hi Tom,

It worked!
XY=# create extension hstore from unpackaged;
CREATE EXTENSION
XY=# \dx
                             List of installed extensions
    Name     | Version |   Schema   |                   Description
-------------+---------+------------+--------------------------------------------------
 adminpack   | 1.0     | pg_catalog | administrative functions for
PostgreSQL
 hll         | 1.0     | public     | type for storing hyperloglog data
 hstore      | 1.2     | public     | data type for storing sets of (key,
value) pairs
 pgstattuple | 1.0     | public     | show tuple-level statistics
 plpgsql     | 1.0     | pg_catalog | PL/pgSQL procedural language
(5 rows)

Thanks for help.

T.

Perhaps what you've got there is an hstore installation from before
extensions existed?  Try "create extension hstore from unpackaged"
to update it.

When you don't know what you are doing, trying to fix it with manual surgery
on the system catalogs is a good way to make things worse.
