nbtree: reduce code redundancy by using _bt_getmeta() in _bt_gettrueroot()
Chao Li <li.evan.chao@gmail.com> — 2026-01-15T08:10:42Z
Hi Hackers, I noticed this while reviewing [1]. _bt_gettrueroot() performs the same metapage checks as _bt_getmeta(), so using _bt_getmeta() here removes the duplicated code. Build passed without warning and "make check" passed.

These two code snippets are exactly identical, so removing the redundant code is reasonable. As can be seen from the contextual comments, this is not a performance-critical path either, so we don’t need to worry about the performance overhead caused by function calls. I also checked the changes made in commit dd299df, which essentially does the same thing for the function _bt_getrootheight.

Ok, committed. - Heikki
