I am having trouble rebasing the patch to the current head. I resolved all conflicts, but there are changes to the codebase that I cannot accommodate.

issue 1: `pg_constraint.c:564`
I need to check that `conppeqop` is not null and copy it but I don't know how to check its type since its a char*

issue 2: `matview.c:768`
I need to pass `fkreftype` but I don't have it in the rest of the function


In other news, I am currently working on exhaustive tests for the GIN operator, but some pointers on how to do so would be appreciated.

Regards,
Mark Rofail

I was wondering if anyone knows the proper way to write a benchmarking test for the @>> operator. I used the below script in my previous attempt https://gist.github.com/markrofail/174ed370a2f2ac24800fde2fc27e2d38
The script does the following steps:

1. Generate Table A with 5 rows
2. Generate Table B with n rows such as:
every row of Table B is an array of IDs referencing rows in Table A.

The tests we ran previously had Table B up to 1 million rows and the results can be seen here :

How would we change this so it would be more exhaustive and accurate?
