Replace tests like
else if (pg_strcasecmp(prev4_wd, "CREATE") == 0 &&
pg_strcasecmp(prev3_wd, "TRIGGER") == 0 &&
(pg_strcasecmp(prev_wd, "BEFORE") == 0 ||
pg_strcasecmp(prev_wd, "AFTER") == 0))
with new notation like this:
else if (TailMatches4("CREATE", "TRIGGER", MatchAny, "BEFORE|AFTER"))
In addition, provide some macros COMPLETE_WITH_LISTn() to reduce the amount
of clutter needed to specify a small number of predetermined completion
alternatives.
This makes the code substantially more compact: tab-complete.c gets over a
thousand lines shorter in this patch, despite the addition of a couple of
hundred lines of infrastructure for the new notations. The new way of
specifying match rules seems a whole lot more readable and less
error-prone, too.
There's a lot more that could be done now to make matching faster and more
reliable; for example I suspect that most of the TailMatches() rules should
now be Matches() rules. That would allow them to be skipped after a single
integer comparison if there aren't the right number of words on the line,
and it would reduce the risk of unintended matches. But for now, (mostly)
refrain from reworking any match rules in favor of just converting what
we've got into the new notation.

PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: http://www.postgresql.org/download See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions.
