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 logical solution. 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 well Note: This now requires snprintf(), which, if necessary, is taken from src/backend/port. This is certainly a little weird, but it should suffice until a source tree cleanup is done. Enjoy. -- Peter Eisentraut Sernanders väg 10:115
