Summary: After upgrading, edit any page results in the
                    following error: "Error: 1 ERROR: relation
                    "text_old_id_seq" does not exist"
           Product: MediaWiki
           Version: 1.16.0

         Component: Database

I used the config script on the web to upgrade the MediaWiki from 1.15.3 to
1.16.0. The following errors were reported by the config script:

Setting the search path for user "wiki" ...OK
Connected to postgres 8.1.19
There are already MediaWiki tables in this database. Checking if updates are
... search_path for user "wiki" looks correct (mediawiki, public)
... default value of "client_min_messages" is correctly set to "error" for user
... default value of "DateStyle" is correctly set to "ISO, YMD" for user "wiki"
... default value of "TimeZone" is correctly set to "GMT" for user "wiki"

Updating sequence names

Warning: pg_query() []: Query failed: ERROR: syntax error at
or near "RENAME" at character 65 in

... table "category" already exists
... table "mediawiki_version" already exists
... table "mwuser" already exists.

The 'sequence update' part failed. I traced the source of the above error to
mediawiki-1.16.0/maintenance/postgres/archives/patch-update_sequences.sql. The
'ALTER SEQUENCE' is invalid syntax and I replaced these statements with 'ALTER
TABLE' as per postgres documentation. I reloaded the database from 1.15.3 and
tried to upgrade again and upgrade went without a hitch. I can see the renamed
sequences in mediawiki schema.

However, when I try to update any page I get the following error:

MediaWiki internal error.

Do I need to upadte cache or something? The above error happens when I try to
save a page after updating. Thanks in advance.
