Peter Eisentraut 74618e2b82 Another round of those unportable config/build changes :-/ * Add option to build with OpenSSL out of the box. Fix thusly exposed bit rot. Although it compiles now, getting this to do something useful is left as an exercise. * Fix Kerberos options to defer checking for required libraries until all the other libraries are checked for. * Change default odbcinst.ini and krb5.srvtab path to PREFIX/etc. * Install work around for Autoconf's install-sh relative path anomaly. Get rid of old INSTL__OPTS variables, now that we don't need them anymore. Use `gunzip -c' instead of g?zcat. Reportedly broke on AIX. * Look for only one of readline.h or readline/readline.h, not both. * Make check for PS_STRINGS cacheable. Don't test for the header files separately. * Disable fcntl(F_SETLK) test on Linux. * Substitute the standard GCC warnings set into CFLAGS in configure, don't add it on in Makefile.global. * Sweep through contrib tree to teach makefiles standard semantics. ... and in completely unrelated news: * Make postmaster.opts arbitrary options-aware. I still think we need to save the environment as well.		25 years ago

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.
