FW: crash problem

Looking even closer at the docs, it appears that my pg_triggers table should
have a column tgdeferrable BOOL, but it does not. When I try to create it I
get:
devtest=# alter table pg_trigger add column tgdeferrable BOOL;
ERROR: ALTER TABLE: relation "pg_trigger" is a system catalog

Is there some way that I can FORCE the creation or somehow get that column
back in there just so I can do a dump???

Subject: crash problem

My database crashed earlier. It's starts up fine, and I can use it, but I
cannot back it up, it reports this error:
bash$ pg_dump -t letter_tag_execute_types devtest >
bkletter_tag_execute_types
getTables(): SELECT (for TRIGGER) failed. Explanation from backend: 'ERROR:
No
such attribute or function 'tgdeferrable'
'.

I get the same error if I try to do dumpall.

I try looking at the triggers table and this is what I get:
devtest=# select * from pg_trigger;
ERROR: Relation pg_trigger does not have attribute
devtest=# \d pg_trigger
Table "pg_trigger"
Attribute | Type | Modifier
----------------+------------+----------
tgrelid | oid |
tgname | name |
tgfoid | oid |
tgtype | smallint |
tgenabled | boolean |
tgisconstraint | boolean |
tgconstrname | name |
tgconstrrelid | oid |
tginitdeferred | boolean |
tgnargs | smallint |
tgattr | int2vector |
tgargs | bytea |
Indices: pg_trigger_tgconstrname_index,
pg_trigger_tgconstrrelid_index,
pg_trigger_tgrelid_index

I ran a vacuum, and it did worked, but did not fix this corruption problem.

Nothing meaningful appears in the log, just messages about the "backend
terminated unexpectedly".

What do I do now? I was hoping to upgrade to 7.2.1 this weekend, but if I
cannot back it up again, I will loose all of todays work, which was pretty
significant, I added much tables and populated a bunch also.

Any ideas is appreciated.
