Compare what data changed in your Postgres database between two points in time.

It works by just dumping out the tables into files in /var/tmp/pgdiff, so if you have a really large database, then you might have a bad time.

Start/end a capture (use the same key a second time)

$ pgdiff postgresql://user:password@host:port/db_name -k some_key

Delete existing captures

# all
$ pgdiff postgresql://user:password@host:port/db_name -d
# some_key only
$ pgdiff postgresql://user:password@host:port/db_name -d -k some_key

Limit capture to certain tables only

# no need to use -t on the second time
$ pgdiff postgresql://user:password@host:port/db_name -k some_key -t "table_a,table_b,other table"
