| To not compile in support for databases you don't use, there is a version identifier for each. To use PgDatabase, set -fversion=dbi_pg . |

Thanks. Work, but there is another error:
| Code: | import dbi.all;
import dbi.pg.all;
int main ( char [][] args ) {
PgDatabase db = new PgDatabase ( );
return 0;
} |
$ gdc test.d -I/usr/include/d -I/usr/include/d/4.1.2 -fversion=Posix -fversion=dbi_pg
test.d:5: Error: cannot create instance of abstract class PgDatabase |

| I have fixed that particular problem and your example compiles now on my machine, but I think you will find that the PgDatabase implementation in general is lacking. If you know libpq, your help would be appreciated. |

Unfortunately I just beginner ... But I can catch bugs in UNIX-like OS :)

Yes, I can compiling it too, here is summary :)
| Code: | | gdc test.d -o test -I/usr/include/d -I/usr/include/d/4.1.2 -I/usr/include/d/4.1.2/i686-pc-linux-gnu -fversion=Posix -fversion=dbi_pg -ldbi -lpq -lgtango |
Thanks larsivi for help! |
