Report generation

I've been doing a lot of playing and learning with postgres, and if the
subject of report generation is in either the distribution docs or either of
the two books I've read, I cannot recall seeing the discussion.

What are my options for getting reports from a database, particularly for
printing?

For example, I'm porting my old A/P module to postgres and C. How do I
print checks from data within the database? Or, print payable reports and
transaction journals? I've not seen references to report generators anywhere
so I assume they have to be hand-crafted in C, perl, python or something
similar.

All pointers greatly appreciated.

Many thanks,

Rich
