This module seems a valid alternative to mod-auth-pgsql that you tried
before, and filed bug #1698758. With DBD + pgsql, you can use your {SHA}
style password hashes.
I just tried the following hashes (all "secret"):
andreas-clear | secret
andreas-crypt | 5TGnWmWlHTJ/2
andreas-sha
According to https://httpd.apache.org/docs/2.4/mod/mod_authn_dbd.html:
You have global DBD options, and then you have to use further Auth*
options inside elements. The dbd module is used by other
mod_auth_* modules such as mod_auth_basic.
