Thanks Francis.
Meanwhile just gone through usage of perl in postgres function. In turn,
this Postgres function can be called in pg_bulkload. I think, this task can
be done. Let me give a try.

Yes.
I can able to apply those mentioned transformation in pgloader &
pg_bulkload-SQL filter. Yet to take performance stats. Meanwhile, I'm trying
to figure out the other best possible option. We are counting more on
performance, error & audit handling.
Thanks

Thanks Francis.That seems to be a good solution.
Thought to use pg_bulkload, a third party library instead of copy, where
reject handling can be done in efficient way. Transformation(FILTER)
functions can be implemented with any languages in pg_bulkload before it was
loaded to table. SQL, C, PLs
Thanks Jan
I'm converting the code from Oracle to Postgres. Both version of code will
be available for different users.
In Oracle, doing these kind of transformation in SQL loader. Need to follow
the same kind of approach in Postgres. SQL filter approach was very easy in
terms of coding. From
Gurus,
Reading the data from file and loading it using pg_bulkload- C filter. As
per documentation, C filter is much faster than SQL filter.
I'm new to C. Gone through this documentation. Not clear, how to start.
