Hello Guys,
I have a case that I would like you to help me with.
I have a partitioned table in postgresql version 9,5 to which I select and it returns data perfectly, but when I want to make a backup of the table, it only saves the structure without records.
It should be noted that I am not making a backup of the structure, but of the data or complete, but it does not back up the data anyway.
When consulting the administrator, he informs me that it is a partitioned table and that it is always zero, but the data is in its "daughter" tables and that the select that it returns is the information that is housed in all its daughter tables.
That is correct.
Now, given this, I wanted to know if there is any way to make a backup of the table that throws all the data from its child tables into a flat file.
Flat file as in a CSV file?
Is it possible to perform this action?
If you want to export it to a CSV (or tab-separated, etc, etc) flat file, then -- if using psql, use the COPY or \COPY command; instead of simply specifying a table name, copy the
query (SELECT * FROM parent_table).
If that's not what you mean, please clarify.
