Psql support

2.11. Psql support

Information about FTS objects can be obtained in psql using a set of commands

\dF{,d,p}[+] [PATTERN]

Optional + used to produce more details.

Optional parameter PATTERN is a name (can be schema-qualified) of the FTS object. If PATTERN is not specified, then information about default object (configuration, parser, dictionaries) will be displayed. Visibility of FTS objects conforms PostgreSQL rule. PATTERN can be a regular expression and should apply separately to schema name and object name. Following examples illustrate this.
