At some point back in the last century, somebody felt that reading all of pg_type twice was cheaper, or at least easier, than using repalloc() to resize the Typ[] array dynamically. That seems like an entirely wacko proposition, so rewrite the code to do it the other way. (To add insult to injury, there were two not-quite-identical copies of said code.) initdb.c's readfile() function had the same disease of preferring to do double the I/O to avoid resizing its output array. Here, we can make things easier by using the just-invented pg_get_line() function to handle reading individual lines without a predetermined notion of how long they are. On my machine, it's difficult to detect any net change in the overall runtime of initdb from these changes; but they should help on slower buildfarm machines (especially since a buildfarm cycle involves a lot of initdb's these days). My attention was drawn to these places by scan-build complaints, but on inspection they needed a lot more work than just suppressing dead stores :-( |

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: https://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 https://www.postgresql.org/download/. For more information look at our web site located at https://www.postgresql.org/.
