The answer is simple: don't do that. You do not need to, and should
not, convert to string form
Thanks Tom for your interest.
I could find a workaround for the issue wherein the value of type
which is not stored "by value" and has fixed data length, is being
stored in string format to the relation.
While retrieving from relation, this value is converted by using
"coerce_to_specific_type()"

Perhaps you should study the ANALYZE code. AFAICS your requirements are
not different from those of the pg_statistic data store. You should do
things the same way they are d

Oh, hm. I think you need to look at typlen instead of typbyval.
But you have an additional problem for
Thanks Greg, for showing interest.
The problem here is I need to store values of different types into bytearray
column of relation.

Hi,
I am trying to write values of different types to relation using following
code.
if(typbyval)
{
min_ba = (bytea *) palloc(len+1+VARHDRSZ);
memcpy(VARDATA(min_ba), &min_datum, len);
SET_VARSIZE(min_ba, len+VARHDRSZ);
