RE: version 1 C-Language Functions

Those functions demonstrate copying text input.  I am not.  I'm trying to
use a parameter entered as part of a select statement that will generated.
I need PG_GETARG_CSTRING(x) for this task, not PG_GETARG_TEST.  The way the
program will work is it will sandwitch together the select statement into a
single var (w/ the param in the middle) using strcat and then feed it to SPI
for execution.  No example that I have run across illustrates how to convert
a param entered to be used w/ regular c functions (in this case strcat).

Read the "Programmer's Guide", part II "Server Programming", section 13.4.3
"Version-1 Calling Conventions for C-Language Functions". Look at the
example
functions copytext and concat_text.
