22 * RawParseMode determines the form of the string that raw_parser() accepts:
23 *
24 * RAW_PARSE_DEFAULT: parse a semicolon-separated list of SQL commands,
25 * and return a List of RawStmt nodes.
26 *
27 * RAW_PARSE_TYPE_NAME: parse a type name, and return a one-element List
28 * containing a TypeName node.
29 *
30 * RAW_PARSE_PLPGSQL_EXPR: parse a PL/pgSQL expression, and return
31 * a one-element List containing a RawStmt node.
32 *
33 * RAW_PARSE_PLPGSQL_ASSIGNn: parse a PL/pgSQL assignment statement,
34 * and return a one-element List containing a RawStmt node. "n"
35 * gives the number of dotted names comprising the target ColumnRef.
