Ok, you say that you cannot drop
and recreate, so you need to do this via alter statements only? Thatâs
obviously going to complicate matters, as a straight dump, drop, recreate,
restore would be the fastest and by far simplest method.
So, Ideally, youâll need
to do a table def comparison over the two databases, and generate the necessary
sql to amend the tables in test accordingly?
Querying the pg_catalog/information_schema
over the two dbâs should give you the table ddl from which you can diff,
and then generate the alter statements from the results.

Well,
I canât just go dropping and recreating tablesâ it needs to create
the correct alter statements if existing tables and or functions already exist.
Secondly,
when Iâm finished changing the structure, I need to be able to select the
list of tables that will have content updates.
Using
a script might be more work maintaining then itâs worth. I have a backup
utility that can do the job, but 3 tedious steps per schema, that only work
about 10% of the time (and no batching options so that I can create a list of
actions and run the list).

Iâm assuming that this
needs to be tightly controlled and as such a replication tool is out of the
question?
In that case; The first thing to
pop into my head here would be to use either use shell scripting, or to use the
pg API and write a c program to handle it.
I remember doing something very
similar with Oracle a few years back.

Hello!
First
day on the new mailing list as I have need of some expertâs advice.
I
need to be able to quickly apply the structure updates from a development
database to a testing database, and do selective data updates (like on lookup
tables, but not content tables).
Any
help would be appreciated!
Brad
