This is not your problem.

As you understand, I think, with streaming replication all files, including indexes, are exactly duplicated on the
replica.If the OS on the two sides have different glibc versions which have different collations, then the index
structureof the primary will be a corrupted index on the replica. You have to fix your OS version incompatibility, or
moveto a version of postgres which can use ICU collations and make sure that library is compatible on both sides.
