PostgreSQL 8.0 gives more context:
ERROR: syntax error at or near "$1" at character 150
QUERY: SELECT CAST(extract(year from min(scan_timestamp)) || extract(month from min(scan_timestamp)) || extract(day
frommin(scan_timestamp)) AS date) AS $1 FROM inventory.tbl_scanner
CONTEXT: PL/pgSQL function "commit_scanner_data" line 9 at SQL statement
LINE 1: ...xtract(day from min(scan_timestamp)) AS date) AS $1 FROM i...
The offending code is:

PL/pgSQL appears confused over a column alias with the same name
as a variable in the DECLARE section (v_inventory_date).
