a134ee3379 Update documentation on may/can/might: 
Standard English uses "may", "can", and "might" in different ways:

        may - permission, "You may borrow my rake."

        can - ability, "I can lift that log."

        might - possibility, "It might rain today."

Unfortunately, in conversational English, their use is often mixed, as
in, "You may use this variable to do X", when in fact, "can" is a better
choice.  Similarly, "It may crash" is better stated, "It might crash".

Also update two error messages mentioned in the documenation to match.

b2c4071299 Redesign query-snapshot timing so that volatile functions in READ COMMITTED 
mode see a fresh snapshot for each command in the function, rather than
using the latest interactive command's snapshot.  Also, suppress fresh
snapshots as well as CommandCounterIncrement inside STABLE and IMMUTABLE
functions, instead using the snapshot taken for the most closely nested
regular query.  (This behavior is only sane for read-only functions, so
the patch also enforces that such functions contain only SELECT commands.)
As per my proposal of 6-Sep-2004; I note that I floated essentially the
same proposal on 19-Jun-2002, but that discussion tailed off without any
action.  Since 8.0 seems like the right place to be taking possibly
nontrivial backwards compatibility hits, let's get it done now.

909a8377db The valid return value should be MODIFY instead of MODIFIED. 
The error message said so :-)

In 25.3. Using PL/Python

        If the trigger "when" is BEFORE, you may return None or "OK"
        from the Python function to indicate the tuple is unmodified, "SKIP"
        to abort the event, or "MODIFIED" to indicate you've modified the tuple.

33a82e7fd8 Here's some matching documentation, including some other 
undocumented items in TD.

Should doc patches alse be sent to pgsql-patches, or do I
have to subscribe to pgsql-docs?

The archive link for pgsql-patches is broken, and I don't
see any patches in spot checking the archive for pgsql-docs.
