FAQ
I am using PostgreSQL 8.0.1 in Windows 2003.

I am getting the following error on a trigger function; can't figure out what is wrong:
ERROR: syntax error at or near ":" at character 9
QUERY: SELECT := ''
CONTEXT: PL/pgSQL function "update_rpt_history" line 56 at block variables initialization
Google shows only a few of these errors, but still can't figure out what is the cause or what to do to
fix / avoid this.

What I did so far / questions:
- looked at all assignment operators ( := ), they look fine to me
- looked for a SELECT := '', but found none; and, line 56 has no 'SELECT' statement
- question: not sure where 'block variables initialization' is; error message does not show up in error
codes of PostgreSQL doc manual
- question: where do the 'RAISE' commands display? Was using them to diagnose what line the
function failed on.
- not sure how PostgreSQL counts lines; assume it will count all lines except comment lines (--);
if true, the 56th line would be an attempt to store a trigger variable:
process_name := TG_ARGV[0];

Here is what the first 100 lines or so look like:
