The need for dumping from such ancient servers has decreased to about nil in the field, so let's remove all the code that catered to it. Aside from removing a lot of boilerplate variant queries, this allows us to not have to cope with servers that don't have (a) schemas or (b) pg_depend. That means we can get rid of assorted squishy code around that. There may be some nonobvious additional simplifications possible, but this patch already removes about 1500 lines of code. I did not remove the ability for pg_restore to read custom-format archives generated by these old versions (and light testing says that that does still work). If you have an old server, you probably also have a pg_dump that will work with it; but you have an old custom-format backup file, that might be all you have. It'd be possible at this point to remove fmtQualifiedId()'s version argument, but I refrained since that would affect code outside pg_dump. Discussion: <2661.1475849167@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.
