Documentation: in a pgsql: client configuration, the setting

"dbname" is required, but ignored when the setting "hosts"
|
||||
contains an URI with a database name. File: proto/pgsql_table.

20241025
|

|

Cleanup: accept any well-formed URI prefix as a pgsql: client
|
||||
connection target (the PostgreSQL URI parser decides what
|
||||
is allowed). The dbname setting is now optional if the hosts
|
||||
setting specifies only URIs. Files: util/valid_uri_scheme.[hc],
