This is the second try at this, after fcef1617295 failed miserably and had to be reverted: as it turns out, libpq cannot depend on libpgcommon after all. Instead of shuffling code in the master branch, make that one just like 9.4 and accept the duplication. (This was all my own mistake, not the patch submitter's). 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. Author: David Fetter, Andrew Dunstan. Some editorialization by me (probably earning a Gierth's "Sloppy" badge in the process.)

PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. 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. The latest version of this software may be obtained at http://www.postgresql.org/download/. For more information look at our web site located at http://www.postgresql.org/.
