Hello.
We are trying to migrate from Informix 9.4 to PostgreSQL. As part of migration we are porting our client application.
So we need reimplement such functionality:
1. Declare a cursor using to _parameterized_ SELECT statement. It should be possible to specify cursor's name (and, perhaps, the statement) dynamically.
2. Open that cursor (in another C-function) passing parameters to it.
3. Fetch records from result set.
4. Close the cursor.
Steps 2-4 may be repeated if necessary.
Is it possible with ecpg or libpq?

Best regards,
Aleksey
