No, the value is read from the server and depends on how the server was
compiled. Run 'show integer_datetimes;' in psql or whatever client you are
using to see the value. 
Pqconnection has detected that it is 'on' on your server. You can check with
above command to see if the server agrees with that.
With integer_datetimes on the datetime is returned as an int64 with the
number of microseconds since 2000-01-01 00:00:00 UTC, hence the 
dbl^ := pint64(buffer)^/1000000;
Dbl is a Pdouble, so the alignment problem could indeed come from there. The
buffer returned by the driver is correct because just before you have
pint64(buffer)^ := BEtoN(pint64(CurrBuff)^); CurrBuff being the pointer

Now, you are getting a SIGSEGV, not a SIGBUS which is what you would get for
an alignment problem.
