I'd think Java would be able to do array --> table and table --> array
very quickly. Certainly, PHP and Perl do.
Also, you can use a custom aggregate to give yourself a comma-delimited
list from a subtable (see the article on custom aggregates at
techdocs.postgresql.org) However, custom aggregates are slow and
Java's array-handling is probably faster.
