This commit adds more coverage for utility statements so as it is possible to track down all the effects of query normalization done for all the queries that use either Const or A_Const nodes, which are the nodes where normalization makes the most sense as they apply to constants (well, most of the time, really). This set of queries is extracted from an analysis done while looking at full dumps of the regression database when applying different levels of normalization to either Const or A_Const nodes for utilities, as of a minimal set of these, for: - All relkinds (CREATE, ALTER, DROP) - Policies - Cursors - Triggers - Types - Rules - Statistics - CALL - Transaction statements (isolation level, options) - EXPLAIN - COPY Note that pg_stat_statements is not switched yet to show any normalization for utilities, still it improves the default coverage of the query jumbling code (not by as much as enabling query jumbling on the main regression test suite, though): - queryjumblefuncs.funcs.c: 36.8% => 48.5% - queryjumblefuncs.switch.c: 33.2% => 43.1% Reviewed-by: Bertrand Drouvot Discussion: https://postgr.es/m/Y+MRdEq9W9XVa2AB@paquier.xyz
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/.
