Well, it seems that i have to build the scan operator myself. Even the
FunctionScan will make all the function calls and stores the result in a
tuuplestore. So, all the delay will be occured only at the first function
invocation.

I need to select all tuples from a table, but need them to be fetched with a
constant delay (say 1 sec) between every consecutive tuples.
The first idea that came up to my mind is to create a DelayedSeqScan
operator, and put delay before returning the scanned tuple.
Can I do this functionality
Why not do this on the client side? I'm just curious as to the benfit
of doing this on the server.

I need this for a side project. Is there a way to do something like this:
SELECT *
FROM DelayedTable('tablename', 5);
DelayedTable provides me with one tuple every 5 seconds.

You can probably build a sleep() function in C, and then use that to
cause delaying in a PL/pgSQL

No, at my knowledge you'll obtain the first tuple only when
the function exit.
