The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/12/catalog-pg-type.html
Description:

Regarding https://www.postgresql.org/docs/12/catalog-pg-type.html
There is an error in the documentation, at least for version 12 (cannot
check for version 16),  in the ‘References ‘ column, for the following
entries:

Table 51.63. pg_type Columns
Name         Type         References
----        ----        -----------
typinput     regproc     pg_proc.oid
typoutput     regproc     pg_proc.oid
typreceive     regproc     pg_proc.oid
typsend     regproc     pg_proc.oid
typmodin     regproc     pg_proc.oid
typmodout     regproc     pg_proc.oid
typanalyze     regproc     pg_proc.oid

The correct reference is pg_proc.proname
