I have now written some of them: + + time_difference(time1, time2) ,also defined as operator '-' + hour(time) + minutes(time) + seconds(time) + asMinutes(time) + asSeconds(time) + currentTime() + currentDate() + +The file can be compiled as shared library and loaded as dynamic module +without need to recompile the backend. This can also be taken as an example +of the extensibility of postgres (user-defined functions, operators, etc). +I would be nice to see more of these user contributed modules posted to this +list and hopefully accessible from the Postgres home page. + + |
