Text parser rewritten: - supports multibyte encodings - more strict rules for lexemes - flex isn't used Add: - tsquery plainto_tsquery(text) Function makes tsquery from plain text. - &&, ||, !! operation for tsquery for combining tsquery from it's parts: 'foo & bar' || 'asd' => 'foo & bar | asd'

Re-run pgindent, fixing a problem where comment lines after a blank comment line where output as too long, and update typedefs for /lib directory. Also fix case where identifiers were used as variable names in the backend, but as typedefs in ecpg (favor the backend for indenting). Backpatch to 8.1.X.
