amcheck: Add a GIN index to the CREATE INDEX CONCURRENTLY tests
The existing CREATE INDEX CONCURRENTLY tests checking only B-Tree, butcan be cheaply extended to also check GIN. This helps increasing testcoverage for GIN amcheck, especially related to handling concurrent pagesplits and posting list trees.This already helped to identify several issues during development of theGIN amcheck support.Author: Mark Dilger <mark.dilger@enterprisedb.com>Reviewed-By: Tomas Vondra <tomas.vondra@enterprisedb.com>Reviewed-By: Kirill Reshke <reshkekirill@gmail.com>Discussion:https://postgr.es/m/BC221A56-977C-418E-A1B8-9EFC881D80C5%40enterprisedb.com
