pgtcl - libpgtcl: * Add new pg_dbinfo options "dbname", "user", "pass",

Log Message:
-----------
* Add new pg_dbinfo options "dbname", "user", "pass", "host", "port",
"options", "status", "transaction_status", "error_message",
"needs_password", "used_password", "used_ssl" to provide Tcl access
to libpq connection parameter values established at connection time.

* Fixed bug where pg_dbinfo would get a segmentation violation if passed
an invalid connection handle.

* Version bump to 1.9.
