Hello all,

I'm working on a pg database that should be able to run commands on 
certain conditions. E.g. whenever a date is stored in column X of table 
Y, an email should be sent to user Z. Creating a triggered function is 
easy enough but how do I invoke the command? Also, I want to use 
variables in the executed command, something like:

	m_address := ''me(at)myself(dot)org'';
	m_subject := ''this is a test'';
	runcommand(''mail -s '' + m_subject + m_address);

I guess the answer is very obvious, but I couldn't find it. TIA for any 
help!
