Howdy:
Running PostgreSQL 7.2.1 on RedHat Linux 7.2 kernel 2.4.7-10.
This past weekend, I was trying to test PostgreSQL 7.2.2 on a backup
box. I did a pg_dump of my production database (7.2.1) and tried
to load it on my development DB (7.2.2). When I did, I got
a slew of errors pertaining to invalid data inside the tables.
For example, if I tried to restore a table that has an invalid date in
the date column, an error is generated. My questions are:
1) If the errors are generated, does that mean that the record is
skipped each time there is invalid data in the table or the table is
skipped?
2) How can I check the integrity of the new database if pg_dump
is not loading all of the information from the production database?
3) I tried doing something like:
[snip]
pg_dump -i -Fc -S postgres -d testdb | pg_restore -v -h 192.168.0.2 -S \
postgres -d testdb
[/snip]
And got a list or errors - mostly because a few tables did not have read
permissions set to them. I have to go threw them by hand to change permissions
(It's odd: how is it that you can create a table but the table will NOT have
the owner or it's permissions on it? like so:
[snip permissions]
testdb=> \dp forums_auth
Access privileges for database "testdb"
Table | Access privileges
-----------------------------------+-------------------
forums_auth |
forums_auth_id_seq |
[/snip permissions]
I'm sure I can do a count or something of each table, but, this also
means my backup / recovery method is screwy because I can't
recover anything that PostgreSQL throws errors at.
How is everyone else in the world reloading tables that may have
invalid data?
Thanks!
