old PostgreSQL versions (ISTR less than 7.4, yes coincidentaly
similar to VW version number) have a problem with subselects
using "IN" clauses. These are heavily used by some store
operations. This bit us a while ago, when a repository grew
with a lot of versions. This has much approved, we are
currently running a 8.1 subversion.
Still, size does matter for query response times, so every couple
of years we start a new db and keep the old one for reference.
