You know you have a table with (at least one) corrupted TOAST entry. You want to scan the table and find which row(s) have the corruption.
See Josh Berkus's blog post on TOAST corruption. This program is a translation of the plpgsql version, generalizing it to arbitrary multicolumn PKs. Rewriting this in Python also eliminates the need for transactions, which was a crucial performance problem when running the plpgsql version on large tables.
find_bad_toast --table MY_TABLE --pk PK_COL_1 [ --pk PK_COL_2 ... ] --connect-string 'user=MY_USERNAME host=MY_HOST dbname=MY_DB'
or, if you prefer,
find_bad_toast -t MY_TABLE -p PK_COL_1 [ -p PK_COL_2 ... ] --connect-string 'user=MY_USERNAME host=MY_HOST dbname=MY_DB'
- Create a virtualenv, enter it, then 'pip install -r requirements.txt'
