Some interesting side effects: TOAST pointers are 20 bytes not 32 now; pg_description has a three-column key instead of one. Bugs fixed in passing: BINARY cursors work again; pg_class.relhaspkey has some usefulness; pg_dump dumps comments on indexes, rules, and triggers in a valid order. initdb forced.		2001-08-10 18:57:42 +00:00

Chkpass is a password type that is automatically checked and converted upon
entry.  It is stored encrypted.  To compare, simply compare agains a clear
text password and the comparison function will encrypt it before comparing.
It also returns an error if the code determines that the password is easily
crackable.  This is currently a stub that does nothing.

I haven't worried about making this type indexable.  I doubt that anyone
would ever need to sort a file in order of encrypted password.

If you precede the string with a colon, the encryption and checking are
skipped so that you can enter existing passwords into the field.

On output, a colon is prepended.  This makes it possible to dump and reload
passwords without re-encrypting them.  If you want the password (encrypted)
without the colon then use the raw() function.  This allows you to use the
type with things like Apache's Auth_PostgreSQL module.
