Обсуждение: Postgre 8.0 vs 7.3

Hi,

We have a production environment running postgre 7.3.4
under linux. We are thinking about setting up a
windows only development environment, which would mean
we have to run postgre 8.0 on a windows machine.

Question is, will the code developed under 8.0 run
without problems under 7.3.4? We're only concerned
about the actual SQL syntax, SP and trigger
definitions, FK constraints, etc. Ie, are the syntaxes
for the two versions the same or what do we need to
take into consideration here?

Thanks
Charl

Well, if you're using a feature that's new in 8.0 or new in 7.4, it
certainly won't work on 7.3.

Aside from that, you should be OK. Look at the changelogs for details
though, as 7.3 is a couple releases behind.

For development, however, you normally want the same versions in the
development environment as the production environment.

Can yo do the development in 7.3 and then port to 8.0?  That's more
likely to work, as there are plenty of features in 8.0 that don't exist
in 7.3 but not much that's the other way around.
