Re: Problems with unique constraints - Mailing list pgsql-admin

we had OS upgrades, but with the same locale.

Is there any chance to avoid rebuilding of all indexes/constraints by checking the correctness of indexes ?

In case of a change in the locale properties - albeit the name of the locale remained the same - index corruption is possible.

This has been reported on RedHat platforms. The reaction of the PostgreSQL project was to incorporate the locale libraries by ICU. They can be used on demand. If they change, the database server will automatically reindex if necessary.

If something in the OS libraries changes, the database server won't be informed.

When indexes are corrupt (and data are fine), the best solution is to reindex all indexes over varchar and text columns.

Kind Regards,

Holger
