       The  libpqtypes  library  maintains  a  per-thread global error message.  The error message is managed by
       PQgeterror() and PQseterror().

       PQseterror() takes a regular printf compatible format string for setting the libpqtypes error message.

       PQgetErrorField() gets an error field from the last executed query.  The  error  field  is  only  set  by
       PQparamExec  and  PQparamExecPrepared.   When  using  libpq  functions  that return results, like PQexec,
       continue to use PQresultErrorField.

       To clear the libpqtypes error message, call PQseterror() with a  NULL  format  string:  PQseterror(NULL);
       This will also clear error fields.

       None.

PQgeterror() returns the last error message for the calling thread.  It will never return NULL.

       PQgetErrorField() returns the error field, referenced by fieldcode, for the last executed query.  NULL is
       returned if no value exists.
