Re: Any "guide to indexes" exists?

I was asking for these "specific/particular reasons". Im not the database
developer, to be expert on indexes (i know whats btree and hash - gin and
gist are rather mysterious for me).
Ok - btree is fine, but sometimes could be better to use gist - my question
is: when is that "sometimes"? Unless i know how to use the indexes, then
they are useless for me - am i right?

Note: We are using gin with tsearch2 vectors, but here we had no choice -
tsearch2 works only with gin and gist.

Regards,
Jan
