> [dmb>] So how would I go about finding a set of useful conversion functions for basic types (real, decimal, time, etc)?
the basic SQL to C mappings are defined by the H files listed here, http://www.postgresql.org/docs/current/static/xfunc-c.html#XFUNC-C-TYPE-TABLE

[dmb>] Yes, thanks, I found those. Most useful too. What I was looking for was the preferred set of functions that could be used to convert between those types and native C types (that could be used externally with no Postgres includes).
[dmb>] This is fairly easy for ints and reals, but is particularly a problem for all the variable length types (eg text, time and decimal).
