invalid page header in pg_statistic
How do I fix this 7.4.6 issue short of initdb?
invalid page header in block 110 of relation "pg_statistic"
I looked at the block via pg_filedump (included below), and it
does not appear to me to be corrupted, so not sure what I would
zero out, if anything.
TIA.

Take a copy of the file, then you should be able to truncate it.
There's also the zero_damaged_pages option, though I don't know whether
that applies here.
I looked at the block via pg_filedump (included below), and it
does not appear to me to be corrupted, so not sure what I would
zero out, if anything.
I don't see anything odd expect that the header has both a lot of items
and a lot of free space...

Seems odd to me too ... but pg_statistic doesn't contain any
irreplaceable data. See if you can TRUNCATE it. If so, do
an ANALYZE to repopulate it. I don't recall if 7.4 has any
special hoops you'd have to jump through to truncate a system
catalog ...

$ psql -c "truncate table pg_statistic"
ERROR: permission denied: "pg_statistic" is a system catalog
I suppose this means single-user mode is required? Any other
trick to do this during uptime?
TIA.

Scheduled downtime finally arrived last night, and I tried
unsuccessfully to truncate this table:
postgres -D $PGDATA -O -o standalone_log mydb
truncate pg_statistic;
^D
pg_ctl start
psql -d mydb -c "vacuum analyze"
The truncate showed no errors. The vacuum analyze showed the
same error in block 110 of the pg_statistic table. Any ideas
what I'm missing here? Is there another acceptable way to
truncate that table, perhaps "rm file; touch file"?

Really!? Hm, I wonder if you have a reproducible problem. Would it be
possible for you to send me the physical pg_statistic file (off-list)?
I'm curious to see exactly what's wrong with it.
