Thank you for your answer.
my question is not split the data into individual attributes. I want to see the data in the table, but I don't want to be a bytea type. 在2018年7月11日 02:48，Peter Geoghegan<p...@bowt.ie> 写道： On Tue, Jul 10, 2018 at 12:41 AM, 杨杰 <yon...@163.com> wrote: Why does the heap_page_item () of the pageinspect extension not consider providing better user-friendliness? My test table has the following data, and when I look at the t_data I see data of type bytea instead of a more intuitive type, even the same type as the original table. tuple_data_split() can do this (split the data into individual attributes). If you want a friendlier, more visual way of getting this information, then you may find pg_hexedit helpful: https://github.com/petergeoghegan/pg_hexedit -- Peter Geoghegan
