source directory. This involves mostly makefiles using $(srcdir) when they might have used ".". (Regression tests don't work with this, yet.) Sort out usage of CPPFLAGS, CFLAGS (and CXXFLAGS). Add "override" keyword in most places, to preserve necessary flags even when the user overrode the flags. |

Miscellaneous utility functions for PostgreSQL. Copyright (C) 1999, Massimo Dal Zotto <dz@cs.unitn.it> This software is distributed under the GNU General Public License either version 2, or (at your option) any later version. query_limit(n) sets a limit on the maximum numbers of query returned from a backend. It can be used to limit the result size retrieved by the application for poor input data or to avoid accidental table product while playying with sql. backend_pid() return the pid of our corresponding backend. unlisten(relname) unlisten from a relation or from all relations if the argument is null, empty or '*'. It is now obsoleted by the new unlisten command but still useful if you want unlisten a name computed by the query. Note that a listen/notify relname can be any ascii string, not just valid relation names. min(x,y) max(x,y) return the min or max bteween two integers. assert_enable(bool) enable/disable assert checkings in the backend, if it has been compiled with USE_ASSERT_CHECKING. assert_test(bool) test the assert enable/disable code, if the backend has been compiled with ASSERT_CHECKING_TEST. -- Massimo Dal Zotto <dz@cs.unitn.it>
