Re: very concerning, tables hopped from one database to

I have to agree that it was pilot error, but I can't for the life of me
understand how 1/4 of the tables went into the right db and the others
into template1. I saved changed data, droped the hmzbook db, recreated
it and ran psql -U hmz -f db.hmzbook and it put all the tables into
hmzbook as it should have and template1 remained clean. If the
db.hmzbook had more than one \connect in it or something, I wouldn't
hesitate to have considered password/pilot error.

It's never happened before and postgres is one of the most stable
software packages I have ever used. As to your questions, yes the data
was found as expected and table dumps were clean. In my opinion, this
has to be marked up to pilot error as the most reasonable answer with
some as yet unknown reason for the split in tables. Perhaps the socket
blew up and psql reconnected to template1?
