Is this index on a text datatype, and using a collation other than "C"?

Its en_US.UTF-8

 

Also the datatype is bigint

Not that I expect it to crash if that's the cause, I thought it'd just
get confused.

On Ubuntu 16 server,

$ ldd --version

ldd (Ubuntu GLIBC 2.23-0ubuntu11.2) 2.23

On New Server Ubuntu 20,

$ ldd --version

ldd (Ubuntu GLIBC 2.31-0ubuntu9.2) 2.31
