Subject: overwrote THE 'postgres' database - how to recover
Date: Wed, 4 Sep 2019 12:51:04 -0400
Message-ID: <b6cf0e1beb6cb22012a7199bbb95ab91.squirrel@webmail.harte-lyne.ca> (raw)
I was experimenting with creating a copy of an existing database from
a pg_dump sql backup file. I made an misake in failing to delimit an
environment variable and in consequence I issued this command as user
postgres:
I should have used:
gunzip < "$APP_DBNAME".pgsql.gz | pg_restore --create --clean
--user=postgres --dbname="$APP_DBNAME"_copy && vacuumdb
--user=postgres --full --analyze "$APP_DBNAME"_copy
But, instead I did this:
gunzip < $APP_DBNAME.pgsql.gz | pg_restore --create --clean
--user=postgres --dbname=$APP_DBNAME_copy && vacuumdb
--user=postgres --full --analyze $APP_DBNAME_copy
which resulted in this:
gunzip < hll_redmine.pgsql.gz | pg_restore --create --clean
--user=postgres --dbname= && vacuumdb --user=postgres --full
--analyze
Which caused the postgres database to be overwritten with
hll_redmine.pgsql.gz. Is there an easy way to get this back or do I
have to reinitialise the whole thing?
