Thanks for the fast reply buddy.

I have another problem: my FPC version is 2.6.4, and this option is not
available in this version. =/

But just to test, I did it using FPC from trunk, and the following code
returned another error:

[code]
var
  VCon: TPQConnection;
begin
  VCon := TPQConnection.Create(nil);
  VCon.Transaction := TSQLTransaction.Create(VCon);
  try
    VCon.Transaction.Options := VCon.Transaction.Options + [stoUseImplicit];
    VCon.HostName := '127.0.0.1';
    VCon.DatabaseName := 'postgres';
    VCon.UserName := 'postgres';
    VCon.Password := 'postgres';
    VCon.ExecuteDirect(
      'CREATE DATABASE "09_0025" WITH ENCODING=''UTF8'' ' +
      '  OWNER="postgres" TEMPLATE="template1" ' +
      '  LC_COLLATE=''English_United States.1252'' ' +
      '  LC_CTYPE=''English_United States.1252'' '+
      '  CONNECTION LIMIT=-1 TABLESPACE="pg_default"');
  finally
    VCon.Free;
  end;
end;
[/code]

Error:

Very nice. I can create a patch to move this methods to the protected area.
