The -n and -N options were removed. Quoting is now smart enough to supply quotes if and only if necessary. Numerical types are now printed without quotes, except in cases of special values such as NaN. Boolean values printed as true and false. Most string literals now do not escape whitespace characters (newlines, etc.) for portability. SET SESSION AUTHORIZATION argument is a string literal, to follow SQL. Made commands output by pg_dump use consistent spacing and indentation. |

This directory does more than tokenize and parse SQL queries. It also creates Query structures for the various complex queries that is passed to the optimizer and then executor. parser.c things start here scan.l break query into tokens scansup.c handle escapes in input keywords.c turn keywords into specific tokens gram.y parse the tokens and fill query-type-specific structures analyze.c handle post-parse processing for each query type parse_clause.c handle clauses like WHERE, ORDER BY, GROUP BY, ... parse_coerce.c used for coercing expressions of different types parse_expr.c handle expressions like col, col + 3, x = 3 or x = 4 parse_oper.c handle operations in expressions parse_agg.c handle aggregates, like SUM(col1), AVG(col2), ... parse_func.c handle functions, table.column and column identifiers parse_node.c create nodes for various structures parse_target.c handle the result list of the query parse_relation.c support routines for tables and column handling parse_type.c support routines for type handling
