database
Specifies which database name(s) this record matches. The value all
specifies that it matches all databases. The value sameuser specifies
that the record matches if the requested database has the same name as
the requested user. The value samerole specifies that the requested user
must be a member of the role with the same name as the requested
database. (samegroup is an obsolete but still accepted spelling of
samerole.) Superusers are not considered to be members of a role for the
purposes of samerole unless they are explicitly members of the role,
directly or indirectly, and not just by virtue of being a superuser. The
value replication specifies that the record matches if a physical
replication connection is requested, however, it doesn't match with
logical replication connections. Note that physical replication
connections do not specify any particular database whereas logical
replication connections do specify it. Otherwise, this is the name of a
specific PostgreSQL database or a regular expression. Multiple database
names and/or regular expressions can be supplied by separating them with
commas.
If the database name starts with a slash (/), the remainder of the
name is treated as a regular expression. (See Section 9.7.3.1 for
details of PostgreSQL's regular expression syntax.)
A separate file containing database names and/or regular
expressions can be specified by preceding the file name with @.
