compatibility package. This supports importing dumps from past versions
using tsearch2, and provides the old names and API for most functions
that were changed. (rewrite(ARRAY[...]) is a glaring omission, though.)

It required some changes in lexize algorithm, but interface with
dictionaries stays compatible with old dictionaries.

which is neither needed by nor related to that header. Remove the bogus

regression=# select to_tsquery( '\'fotballklubber\'');

(1 row)
So, changed interface to dictionaries, lexize method of dictionary shoud return
pointer to aray of TSLexeme structs instead of char**. Last element should
have TSLexeme->lexeme == NULL.
typedef struct {
/* number of variant of split word , for example
Word 'fotballklubber' (norwegian) has two varian to split:
( fotball, klubb ) and ( fot, ball, klubb ). So, dictionary
should return:
nvariant lexeme
1 fotball
1 klubb
2 fot
2 ball
2 klubb
*/
uint16 nvariant;
/* currently unused */
uint16 flags;
/* C-string */
char *lexeme;
} TSLexeme;
