Bug description:
  I have configured a .htaccess to use libapache2-mod-auth-pgsql to
  authenticate a user against a postgres database. The settings are as
  follows:

  AuthType basic
  AuthName "My Auth"
  Require valid-user
  AuthBasicProvider pgsql
  Auth_PG_authoritative On
  Auth_PG_host 127.0.0.1
  Auth_PG_port 5432
  Auth_PG_user www
  Auth_PG_pwd password
  Auth_PG_database userdb
  Auth_PG_encrypted off
  Auth_PG_pwd_table UserLogin
  Auth_PG_uid_field Username
  Auth_PG_pwd_field ApachePassword

  If I set Auth_PG_encrypted to off, then authentication works but the
  downside is that I have to save plain unencrypted password on the
  database. If I set Auth_PG_encrypted to on, a segmentation fault
  occurs. A typical password to be contained in ApachePassword field is
  the following (for password "password"):
  "{SHA}W6ph5Mm5Pz8GgiULbPgzG37mj9g=" - This matches exactly to what
  would be generated by htpasswd -s.

  Here is the error log entry I get:
  [pid 9662] AH00052: child pid 9670 exit signal Segmentation fault (11)
