Peter Geoghegan	fa41cf8f18	Avoid misinterpreting GiST pages in pageinspect. GistPageSetDeleted() sets pd_lower when deleting a page, and sets the page contents to a GISTDeletedPageContents. Avoid treating deleted GiST pages as regular slotted pages within pageinspect. Oversight in commit `756ab291`. Author: Andrey Borodin <x4mmm@yandex-team.ru>	5 years ago
Heikki Linnakangas	5d1e5c8b75	Check for BuildIndexValueDescription returning NULL in gist_page_items Per Coverity. BuildIndexValueDescription() cannot actually return NULL in this instance, because it only returns NULL if the user doesn't have the required privileges, and this function can only be used by superuser. But better safe than sorry.	5 years ago
Heikki Linnakangas	04eb75e783	pageinspect: Fix relcache leak in gist_page_items(). The gist_page_items() function opened the index relation on first call and closed it on the last call. But there's no guarantee that the function is run to completion, leading to a relcache leak and warning at the end of the transaction. To fix, refactor the function to return all the rows in one call, as a tuplestore.
