Re: Contrib reindex script:

If you are going to implement this is there a way to do it so that it
doesn't lock the tables?  We have had to reindex on a regular basis and
it locks up the tables when we do. The same problem with the old vacuum

Subject: Re: [GENERAL] Contrib reindex script:


Given the real file growth problems we have analyzed over the past
month, I think we need to rethink the tools we give to users.

First, I think we need a section in the admin/maintenance manual talking
about reindex.  (We already have vacuum there, and I think reindex is
something that periodically also should be done.)

Second, reindex on an entire database only works for stand-alone
databases.  Now, I know we can't reindex system tables on a live
database, but should we enable REINDEX all non-system tables  for a
database, similar to how we use vacuum?  Do we need the reindex script
like vacuumdb?
