Format conversion for import in Postgresql

[Ariel.Burbaickij]

Hello dear newsgroup participants,
I have some old proprietary database with
following format for its entries:

Instance of entry (some service information like table number and
position) ^M (newline)
1 Parameter: Value ^M (newline)
2 Parameter: Value ^M (newline)
3 Parameter: Value ^M (newline)

Another instance of entry (some service information like table number
and position) ^M (newline)
1 Parameter: Value ^M (newline)
2 Parameter: Value ^M (newline)
3 Parameter: Value ^M (newline)

Yet another instance of entry (some service information like table
number and position) ^M (newline)
1 Parameter: Value ^M (newline)
2 Parameter: Value ^M (newline)
3 Parameter: Value ^M (newline)

and so on and so on.
My question is: What would be the wise way to import tables of this
kind to
Postgresql, do some tools exist that would allow me to convert the
format
presented to internal format of Postgresql ?
