Subject: [PG95]: new postgres functions

Some time ago I read in the mailing list requests of people looking
|
||
|
|
for more time and date functions. 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.
