Thanks

REINDEX.  There is a contributed utility in contrib that allows you to do it 
for an entire database.

Are you familiar with "REINDEX"? I'm not sure I'd describe what it does as
"defragmentation" but it will recreate an index. See the SQL command
reference in the manuals for details (or the admin manual I think).

Yes.  See REINDEX under "SQL Commands" in the postgresql docs.
