Has anyone got experience with data quality checking, validation and
reporting within PostgreSQL?
How best to use PostgreSQL CHECK Constraint for data quality checking,
validation and reporting?
Can we report on errors in a detailed and specific way? For instance, can
we produce report on specif
Hello,
I want to order tables based on the foreign key so that I can delete tables
one by one without facing "ERROR: update or delete on table "table"

Any help is appreciated.
Thank you in advance.
Best regards

Then Thomas Kellerer's suggestion of having "ON DELETE CASCADE" on the
FK would seem to be what you need. If not then you will need to provide
more information about what you are try

No.
What information is the comment trying to convey?
Are you dumping in plain or custom format?
thank you

Hi， Christian,
That is interesting. Can errors be captured and saved as data with
scripting?

Depends on what the script does.
If the script runs (or is written in) Python the canonical PG
driver (psycopg2/3) will give you such data.

Hi, Kirsten,
That sounds brilliant.
Are there any examples on the web these days?

Hi, Christian,
Brilliant!
Some years ago, I did something similar and saved problematic ones for data
collector.
Now, I am reviewing to see whether there be any elegant way to automate
reporting and giving feedback.

Hi, ALL,
I wonder who ade the decision not to provide an independent build
of the client library of PostgreSQL? And what was the reason behind it?
Its very annoying to build the whole server, just to create a client library
to connect to a remote DB. And then kill the build after the install as

An error message that includes the table name and column name would also
be helpful for non-bulk inserts: a single insert where multiple columns
of a table have the same domain type. The problem gets worse when there
are inserts into multiple tables that have the same domain types
