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*

Schema | Name | Description
