I'm building some partitioning support functions. I'm working on writing one
called clone_indexes_to_partition right now. The idea is to take all the
indexes applied to the parent and create a matching index on the child. Is
there existing code that generates a CREATE INDEX statement given an
indexrelid?

Yes it is :

pg_get_indexdef(index_oid) get CREATE INDEX command for index
