Description Jeff Frost 2014-02-23 20:28:57 UTC 
Looks like the logtrigger stores the bytea columns in 'hex' format in sl_log_* and then the slon chokes on that when replaying against 8.4

error at end of COPY IN: ERROR:  invalid input syntax for type bytea

maybe throw in a check for 8.4 and use encode/decode?

Why would you want to replicate from 9.3 to 8.4?  Just in case you need to fallback after the migration.
