PostGres
Setting up Postgres is a bit different than others, because you need to leave the database field empty to allow PHsPeed to retrieve it's meta-data.
If you have set up the basic postrgesql parameters, use test/show databases to verify the connection. Although the pulldown allows you to select a database: do not! Just select the schema and set the database name in the pdo string.
PDO
pgsql:host={%host%};dbname=postgres;port={%port%}
remark: this setting is based upon the developer edition. You must change the default pdo string to the above. This might change in future editions of PHsPeed.
