psql was already accepting conninfo strings as the first parameter in \connect, but the way it worked wasn't sane; some of the other parameters would get the previous connection's values, causing it to connect to a completely unexpected server or, more likely, not finding any server at all because of completely wrong combinations of parameters. Fix by explicitely checking for a conninfo-looking parameter in the dbname position; if one is found, use its complete specification rather than mix with the other arguments. Also, change tab-completion to not try to complete conninfo/URI-looking "dbnames" and document that conninfos are accepted as first argument. There was a weak consensus to backpatch this, because while the behavior of using the dbname as a conninfo is nowhere documented for \connect, it is reasonable to expect that it works because it does work in many other contexts. Therefore this is backpatched all the way back to 9.0. To implement this, routines previously private to libpq have been duplicated so that psql can decide what looks like a conninfo/URI string. In back branches, just duplicate the same code all the way back to 9.2, where URIs where introduced; 9.0 and 9.1 have a simpler version. In master, the routines are moved to src/common and renamed.
