I applied the v2 patch and tested it.
The patch applied and built successfully.I tested several expression
indexes(function,operator,JSON,and nested-function expressions).The
generated index names are now more descriptive and make it easier to
identify the indexed expression.
I also ran make check.One regression test (indexing) failed.From the
diff,the failure appears to be due to the regression test still
referencing the old autogenerated index names such as
idxpart_expr_idx,while the patched code now generates names such as
idxpart_a_b_idx.
The manual tests behaved as expected,and the new naming scheme
successfully produces more meaningful and distinguishable index names.
The regression failure appears to be related to outdated test
expectations rather than an issue with the patch functionality itself.
