it looks to me like ecpg doesn't know how to convert FILE*
into an SQL value.

I'd say try it without the "EXEC SQL BEGIN DECLARE SECTION;"
but from inspection it appears not to be valid C either.

start by reading the the esqlc manual to figure out how the rules
of C change inside "EXEC SQL BEGIN DECLARE SECTION;".

file:///usr/share/doc/postgresql-doc-8.4/html/ecpg-preproc.html

suggests that "EXEC SQL INCLUDE stdio.h" might help 
but that's not going to fix the broken C code two lines after the
error it's finding.
