Get data back after drop Command

Adarsh Sharma <adarsh.sharma@xxxxxxxxxx> · Mon, 29 Aug 2011 10:18:14 +0530

Dear
all,

Today by mistake I issued a drop table statement in Postgresql
database.

Now is it possible to get that data back through WAL.

My PostgresPLus Version : 8.4

OS : Linux ( CentOs )

My postgresql.conf parameters are :

# WRITE AHEAD LOG

#------------------------------------------------------------------------------

# - Settings -

fsync = on             synchronous_commit = on       wal_sync_method =
fsync                  full_page_writes = on          wal_buffers =
64kB   wal_writer_delay = 200ms commit_delay = 0      commit_siblings =
5   checkpoint_segments = 32

checkpoint_timeout = 5min       checkpoint_completion_target = 0.5  
checkpoint_warning = 30s      archive_mode = on

archive_command = ''      archive_timeout = 0             

Please let me know the steps needed to get data back or ways to do.

Below is the list of files in my pg_xlog directory.

Thanks
