[GENERAL] CURSORs and selects with parameters

[Dan Sugalski]

When using cursors through the libpq interface, do I need to be 
passing in the parameters when I'm FETCHing from them?

I've got some code that uses PQexecParams and does the equivalent of:
   DECLARE a_cursor CURSOR FOR SELECT foo, bar FROM baz WHERE field = $1
   FETCH NEXT a_cursor
but when I get to the FETCH I'm getting back the error:
   ERROR:  no value found for parameter 1
which is fair enough, as I'm not *passing* in any parameters to the 
fetch. (Yes, I double-checked--the parameter count in the 
PQexecParams call is 1 for the cursor declaration, and 0 for the 
fetch) Do I have to?
