## Which issue does this PR close? - Closes #12709. ## Rationale for this change There is no support for concatenating binary strings. There are two ways: 1. Cast binaries to text and then concatenate text type (most common behaviour across DBs as discussed in the ticket) 2. Concatenate binaries and provide binary type (only for Spark) This PR goes with a way (1). We could customise the operator/UDF per-dialect, but it is not currently supported. ## What changes are included in this PR? - Support binary concatenation via a pipe operator - Support binary concatenation in `concat` UDF ## Are these changes tested? Added SLT tests ## Are there any user-facing changes? No -- This is an automated message from the Apache Git Service.
