I want to view deleted records in table from a week ago in order to troubleshoot a data issue. The table has not been vacuumed yet. I was trying to use the pageinspect v1.4 extension but can't seem to convert the t_data to a readable record. Is there an easy way for me to get a SQL to produce all system columns like xmin, xmax along with the visible and invisible records of the table in a readable form.

I was hoping to find a setting similar to what Netezza has "set show_deleted_records=1;" to easily turn this visibility on or off, but it seems that feature was shot down several years ago. As a DBA I want to say that a feature like this is indispensible when troubleshooting data problems in large tables and environments where restores may not always be an option. 

Thanks in advance for any help,
Boyan
