I've got a working pg_hba.conf file in the default location that lists specific users and address (Windows PG14).
The documentation states that I can also list users and address by creating a file which is prefixed by an @ in pg_hba.conf
Multiple user names can be supplied by separating them with commas. A separate file containing user names can be specified by preceding the file name with @.
But any attempt I've made to do this results in a FATAL: could not load pg_hba.conf error
So this type of line works fine
host all user1,user2,user3 10.34.0.0/16 scram-sha-256
But this sort of line results in the FATAL: could not load pg_hba.conf error
host all @myusers 10.34.0.0/16 scram-sha-256
The "myusers" file with no filename extension is in the same directory as the pg_hba.conf and created by the same Windows user that is editing the conf file. The myuser file simply contains the following lines per the documentation
Files included by @ constructs are read as lists of names, which can be separated by either whitespace or commas.
As the @ construct bit seems a bit ambiguous I've also tried a single line with spaces between users as well as one user per line, ie
user1 user2 user3
What am I doing wrong here? I've had a reasonable effort to hunt around for examples and documentation but I didn't find anything other than the official documentation which is a bit limited. Is the @filename syntax even valid for pg_hba.conf?
