Hello all,
I'm writing some extension and I have a hot code path that has a lot of double (C type) data and needs to output NUMERIC tuple data. The current methods I can find in the code to convert sprintf the double to a buffer and then invoke the numeric_in function on them. I've profile my stuff and I'm spending (wasting) all my time in that conversion. Is there a more efficient method of converting a double into a postgres numeric value?
Best regards,
Theo
