Will a DB created under 7.4.2 work with 7.4.5, or do I need to back it up
and restore it to a newly created 7.5.4 DB?

backup your data before upgrading to a new version.

The release notes of upgrades usually indicate whether initdb
is required or not. Generally when the last digit of a version
change it does not require a dump and reload. In this case
the release notes say:

http://www.postgresql.org/docs/7.4/static/release.html#RELEASE-7-4-5


E.1.1. Migration to version 7.4.5

A dump/restore is not required for those running 7.4.X

But migration from 7.4.2 > requires a initdb.

Check the release notes of 7.4.3

The release notes does not seems to say anything like that
can you tell me where u read ?

http://www.postgresql.org/docs/7.4/static/release-7-4-3.html


E.3.1. Migration to version 7.4.3

A dump/restore is not required for those running 7.4.X.


However:

<>http://www.postgresql.org/docs/7.4/static/release-7-4-2.html
does say that dump/initdb/reload is an option to fix 2 errors.
These two errors can also be fixed manually without dump / reload
which is described in same URL.

Since Chris is already using 7.4.2 he may have already fixed it
if the data were imported from < 7.4.2 . If original database was
created using 7.4.2 dump/reload shud not be required for
upgrading to 7.4.5


It is a great timesaver to skip dump/initdb/reload especially
when GIGs' of data is involved. Not just in terms of time but also
minor manual tweaks that are required to be done to dump files
sometime.

Opps !! I was wrong and was in the impression that 7.4.2 > migration
calls for initdb and incidently I have been doing the same for all
my clients :(( Its is such a shame for me.
Anyways Chris Rajesh is correct.

Thanks a lot Rajesh to correct me.
