53.62. pg_ts_parser
The
pg_ts_parser
catalog contains entries
defining text search parsers. A parser is responsible for splitting
input text into lexemes and assigning a token type to each lexeme.
Since a parser must be implemented by C-language-level functions,
creation of new parsers is restricted to database superusers.
PostgreSQL 's text search features are described at length in Chapter 12 .
