Historically guc.c has just refused examples like set work_mem = '30.1GB', but it seems more useful for it to take that and round off the value to some reasonable approximation of what the user said. Just rounding to the parameter's native unit would work, but it would lead to rather silly-looking settings, such as 31562138kB for this example. Instead let's round to the nearest multiple of the next smaller unit (if any), producing 30822MB. Also, do the units conversion math in floating point and round to integer (if needed) only at the end. This produces saner results for inputs that aren't exact multiples of the parameter's native unit, and removes another difference in the behavior for integer vs. float parameters. In passing, document the ability to use hex or octal input where it ought to be documented. Discussion: https://postgr.es/m/1798.1552165479@sss.pgh.pa.us
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/.
