I don't understand this argument. No-one asked what size the LDAP
libraries were when we added support for them. No-one cares that
libssl/libcrypto is as large as glibc. What size the libraries are that
postgresql uses is somewhat irrelevent. It's not like we're forcing
people to install them.

Can you point me to a common platform where postgresql runs and ICU doesn't?


The only one I can see in the buildfarm that isn't mentioned is

If I specify a collation where case and accents are ignored, then GROUP
BY should ignore them too, and regexps should honour that. Moving all
this to the client doesn't seem like a good move at all.
