Hi!
I wanna ask that which pg_dump command line needed if I want to compare
two databases?
I have many DBs, but all of them have two versions a development (local)
DB and the online (web) DB.
When I want to realize a new function, I develop it locally, and later I
sync. it into online DB.
But it is hard: I easily miss some things... :-(
Because of that I want to write some tool that can compare databases.
In DBISAM world I can do it easily, because DBISAM tables very-very near
to Delphi DataSets, and I can compare tables/indexes with Delphi
comparations.
In Firebird it was harder, because if must compare tables, and later other
objects (generators) too... :-(
In PostgreSQL I have two way to compare DBs.
1.) pg_dumps, and textdiff.
2.) get schema (table struct, indexes, etc) from all, and compare them.
The first version is need user SQLs, the second can create alter/create
SQLs automatically...
So please help me with your experience: what is the best solution, what is
the possible problem that make mistakes with this plan, and how to realize
it easily?
Thanks for your help:
