Re: todo: Hash index creation

Wow... not sure how I missed that. I *did* create this schema ages ago, perhaps it wasn't there, or at the time I had
noidea what the implications were. *shrug*<br /> Regards,<br /> - Naz.<br /><br /><br /> Tom Lane wrote: <blockquote

Uh, the manual already does say
   Note: Testing has shown PostgreSQL's hash indexes to perform no better   than B-tree indexes, and the index size and
buildtime for hash indexes   is much worse. Furthermore, hash index operations are not presently   WAL-logged, so hash
indexesmight need to be rebuilt with REINDEX after   a database crash. For these reasons, hash index use is presently
discouraged.

under 11.2 Index Types, as well as various derogatory remarks elsewhere.
