Re: EMERGENCY

Use initdb to build ANOTHER database, leaving your existing one
in tact. Study the difference between the new on and yours.
Next copy some missing files from the new one. The
error messages sound like an "fopen" someplace is failing, posably
if the fopen worked it may proceed to do its re-index???

I think what this shows us it that we need something like an
"fsck" for databases. It should be possable to salvage anything
that is salvageable. This would have to be a stand alone program
that would run with no postmaster running. Maybe called "pgck".

I've had problems like this too and much hand work was required
to repair the damage. Fortunately I logged all my source data in
a way I could "play it back" but in general you can't do that.
