I'm looking specifically for a tool to help compare 2 database schemas
(nominally, production and development) and generate the appropriate SQL
(that can be later executed) to bring the to schema's into sync.
Option1 :
pg_dump -s firstdatabasename > first
pg_dump -s seconddatabasename > second
diff first second
(obviously wont generate SQL to remedy the differences)
Option2:
pgdiff (http://gborg.postgresql.org/project/pgdiff/projdisplay.php)
(old abandoned perl project that doesn't work...)
Option 3:
pgdiff (http://gborg.postgresql.org/project/pgdiff/projdisplay.php)
(old abandoned TCL project which requires AOLServer to run???)
Option 4:
EMS PostgreSQL DB Comparer
(http://www.sqlmanager.net/products/postgresql/dbcomparer)
Slick tool...fairly cheap ($69)...doesnt let you exclude certain
specific tables/sequences/databases, but otherwise, pretty functional.
What does the rest of the postgreSQL admin community do in order to
"bring-live" database schema changes from their development environment
to production? Are there other options/techniques out there?
Any help would be appreciated.
Jeff
