Feature Request: Add SQLSTATE return when the pg_connect() failed to the error text

[EntertainmentOne]

Description

Now, we only get the string desprection, no SQLSTATE.
I must get the SQLSTATE to handle the errors,
Caused by the pg_connect() returns false, I cannot get SQLSTATE by general methods.
Please add this feature to pgsql extension.
