Data files for ICU's i18n support when compiling with make static. Copy one
of the files, depending on your platform, and set the plv8.icu_data variable
in postgresql.conf.
- icudtl.dat - Little Endian architectures (Intel)
- icudtb.dat - Big Endian architectures (Sparc)
For ARM, you will need to figure out which Endianess your hardware and OS is configured for.
NOTE: it is important that the user that Postgres is started with has read access to the file.
