HINT: Please REINDEX it?

I am seeing this in my log...:

ERROR:  index "connect_idx" contains unexpected zero page at block 208
HINT:  Please REINDEX it.


What does this mean? And how do I reindex it?



Regards,

BTJ

It means something bad has happened to an index.  If you're running
an old version of PG then you may be affected by a known bug or you
could have bad hardware.  Did the computer have its power turned off
unexpectedly, as if things are set up right then this could affect
things.

I've just had a quick search and you seemed to be running 8.3.5 before,
there don't seem to be any index related changes since then so maybe
your hardware isn't doing what it's told to!

Just type:

  REINDEX connect_idx;

in psql.

Not any power problem but had a disk problem; guess that might be the cause...
