I have a production server (7.4.9) with, of course, a production
database with 30 tables, 250 functions, types, views, indices, ...
My developers have created new version of the software, that includes
the new version of the datbase. They've changed 6 tables, two dozen
views and almost one hundred stored procedures. Now I need to apply
those changes on the production server.
Is there a way to generate a 'diff' script for the two databases? I'd
write script myself if I'd be able to 'script' just the desired object.
For instance, just the function.
I've seen that I can do pg_dump to a file with pg_dump -Fc, and then I
can do pg_restore -Fc -l <dump.file> to have the list of all the
database objects. There I can see the functions, but how do I (re)create
just the desired function?
What would suit me the best would be a tool/util that would drop each
db.object into a separate file. Then I could create a script wich will
'load' each object from the file when I want it (so I don't have
dependency problems).
Is there a tool like that, or should I stick with pg_dump/pg_restore, or
maybe even going trough information_schema to see all the objects in the
database?
