Information about text search configuration objects can be obtained in psql using a set of commands:

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

An optional `+` produces more details.

The optional parameter _`PATTERN`_ can be the name of a text search object, optionally schema-qualified. If _`PATTERN`_ is omitted then information about all visible objects will be displayed. _`PATTERN`_ can be a regular expression and can provide _separate_ patterns for the schema and object names. The following examples illustrate this:

\=> \\dF \*fulltext\*
       List of text search configurations
 Schema |  Name        | Description
--------+--------------+-------------
 public | fulltext\_cfg |

\=> \\dF \*.fulltext\*
       List of text search configurations
 Schema   |  Name        | Description
