The error "Syntax error at or near '$2'" in Postgres Error 42601 indicates that there is a problem with the syntax of the SQL query being executed. The "$2" part of the error message suggests that there is a parameter being referenced in the query that is not properly defined or is missing. This error can occur when there is a missing comma or quotation mark, or when a parameter is improperly defined. To resolve this error, review the SQL query and make sure all parameters are properly defined and all syntax is correct.
