Does not work since it fetches one byte beyond the source data, and when the phase of the moon is wrong, the source data is smack up against the end of backend memory and you get SIGSEGV. Don't laugh, this is a fix for an actual user bug report. |

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>
