It's very hard to see where you should spend efforts when every "logical query" is split into hundreds of pg_stat_statement entries. Suddenly it's important whether a certain counts of parameters are more frequent than others because in the equally distributed cases they fall out of p_s_s again pretty soon. I think that's probably a worse than average case, but certainly not something only I could have the bad fortune of looking at.
