Is this a logic error or what happens? Problem with foreach

QUESTION

Is this a logic error or what happens? Problem with foreach

Asked 2019-Oct-16 at 03:56

I have a function in c that runs on a Postgresql server called get_ndistinct that returns the statistical value of get_ndistinct for the columns of some tables in a Postgresql database. The fact is that when the foreach is entered twice, the second time, the value loaded in idxcd-> varattnames [i] appears to me as a number, when in fact I should return a column name value. And the number that appears to me matches the value that is returned for get_ndistinct in the previous step of the cycle¿? I really thought a lot and I don't understand why this happens. I don't know if it's a logic error of mine or what's happening. It's very strange, especially since the number coincides with the value returned in the previous step of the cycle ... that I don't know where or how it is loaded in idxcd-> varattnombre [i]¿? To use a debugger, I don't know if I can ... because I use a Makefile. I don't know if I can use debugger with Makefile, I'm new using Linux. I will greatly appreciate an answer please. My source code is as follows:

With the provided information it is impossible to pinpoint the error. Since the foreach loops through the list passed to your function, it depends on the caller of your function what values are in the list. Maybe you should start looking there.

About attaching a debugger, which is unrelated to a Makefile:

Make sure that you compile with the -g option. This happens automatically if you configured PostgreSQL --enable-debug.
Put a sleep(10) at the beginning of your function.
Start a PostgreSQL session and use SELECT pg_backend_pid(); to get the backend process ID.
Call your function and quickly attach the debugger with
