PL/PgSQL is not going to be able to look into your structure if that's
what you want. PostgreSQL treats such things as blobs of memory. You
might define accessor functions though...

int4
SampleGetnCtr1 (Sam *s)
{
return s->nCtr1;
}

Etc...

Then, maybe, you can call the function(s) to get/set it's parts...

SELECT sample_get_ctr1(mysample) INTO foo FROM ... ;
