Magento

I performed the update on a 1.17 installation and it seemed to go smoothly. Now, however, I’m unable to access the store front-end or back-end. Nor can I access the downloader to rerun the process. I’m seeing the following error:

Error in file: “/var/www/html/app/code/core/Mage/CatalogSearch/sql/catalogsearch_setup/mysql4-upgrade-0.7.5-0.7.6.php” - SQLSTATE[42S01]: Base table or view already exists: 1050 Table ‘catalogsearch_result’ already exists

As an adjunct to my prior post, I’m quite certain that the database upgrade process has already run, because MySQL was hogging the CPU for about 2 minutes while all the db schema changes were being made. (This db has 50k customers) That said, the tone of the error, on the surface at least, indicates to me that Magento might believe it hasn’t been done and is trying to do it again.
