* Includes tab completion. It's not magic, but it's very cool. At any
rate it's better than what used to be there.* Does proper SQL "host variable" substitution as pointed out by Andreas Zeugwetter (thanks): select * from :foo; Also some changes in how ':' and ';' are treated (escape with \ to send to backend). This does_not_ affect the '::' cast operator, but perhaps others that contain : or ; (but there are none right now).* To show description with a <something> listing, append '?' to command name, e.g., \df?. This seemed to be the convenient and logicalsolution. Or append a '+' to see more useless information, e.g., \df+.* Fixed fflush()'ing bug pointed out by Jan during the regression test discussion.* Added LastOid variable. This ought to take care of TODO item "Add a function to return the last inserted oid, for use in psql scripts" (under CLIENTS) E.g.,insert into foo values(...);insert into bar values(..., :LastOid);\echo $LastOid* \d command shows constraints, rules, and triggers defined on the table (in addition to indices)* Various fixes, optimizations, corrections* Documentation update as wellNote: This now requires snprintf(), which, if necessary, is taken fromsrc/backend/port. This is certainly a little weird, but it shouldsufficeuntil a source tree cleanup is done.Enjoy.--Peter Eisentraut Sernanders väg 10:115
