Back-patch commit 1c1a7cbd6a1600c9, along with subsequent portability fixes, into all active branches. Also, back-patch commits 696027727 and 596857043 (addition of zic -P option) into 9.1 and 9.2, just to reduce differences between the branches. src/timezone/ is now largely identical in all active branches, except that in 9.1, pgtz.c retains the initial-timezone-selection code that was moved over to initdb in 9.2. Ordinarily we wouldn't risk this much code churn in back branches, but it seems necessary in this case, because among the changes are two feature additions in the "zic" zone data file compiler (a larger limit on the number of allowed DST transitions, and addition of a "%z" escape in zone abbreviations). IANA have not yet started to use those features in their tzdata files, but presumably they will before too long. If we don't update then we'll be unable to adopt new timezone data. Also, installations built with --with-system-tzdata (which includes most distro-supplied builds, I believe) might fail even if we don't update our copies of the data files. There are assorted bug fixes too, mostly affecting obscure timezones or post-2037 dates. Discussion: <13601.1468868947@sss.pgh.pa.us>

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.
