Description:

Please add the note about the limitation characters in connection string.
For example, I think that below explanation should be in the Parameter
section of connection_target.

----
Note that this parameter does not allow the symbols with special meaning of
the URI parts, e.g. "&" and "?". 
-----

I checked some symbols with special meaning of the URI parts whether it is
able to use in connection_target, and I could not connect to database with
the string containing "&" and "?".

I reported this limitation in pg-general.
