Need to include the length of trigger names

Hi all,

I was just looking at the Developer Docs for the "CREATE CONSTRAINT
TRIGGER" command in the SQL Commands reference section.  Noticed it
doesn't include a mention of the maximum length of the trigger "name"
field (31 characters).  I reckon this should be mentioned, and we should
also probably mention it for other similar things in the SQL Commands
reference section.

Regards and best wishes,

Justin Clift
