Information about full text searching 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 should be the name of a text searching object, optionally schema-qualified. If PATTERN is not specified 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:
