What transaction logs? Do you mean pg_clog, or pg_xlog? If the former,
use your latest backup (i.e. forget it, unless you rarely rolled back
any transaction). If the latter, try pg_resetxlog (you will likely lose
some things after the last checkpoint, and some indexes may not be in
correct shape).
What are the exact error messages you are getting?
