Re: I can't restart postgres

Thanks for the help.

I use the pg_resetxlog and the database start again.

Now I have other problem. I try to  view a table using the command
select and I have an  error and I can't view the table.

I wrote the following line in the terminal:

htpoweron=# select * from example_table;

(where example_table is one table of my database)


and I have the following message in the terminal:

ERROR: could not access status of transaction 1557774552
DETAIL: could not read from file  «pg_clog/05CD» at offset 155648:


What I can do to acces that table?

Best regards
