pg_rman 1.2.9 is released.

pg_rman 1.2.9 is released.

This is a minor version up and includes below changes:

• Recalculate checksums in restoring
  Previously pg_rman did not restore data for database with checksum,
  because it rewrote page header in restoring and this caused checksum mismatch.
• Remove unreliable dirent->d_type check in catalog.c
  The current code did not care in a case when d_type = DT_UNKNOWN is returned.
  Because of this, pg_rman show does not work in XFS.
• Better error message for incremental backup failure
• Use PGXS by default in Makefile
• Improve regression tests handling pgbench and pgport
• Some refactoring and removing dead codes, modifying help messages
