Fix description of I/O timing info for shared buffers in EXPLAIN (BUFFERS)
This fixes an error introduced byefb0ef9, that changed thedescription of this field to "shared/local" while these I/O timingsrelate to shared buffers. This information is available whentrack_io_timing is enabled. Note that HEAD has added new counters forlocal buffers in295c36c, so there is no need to touch it. Thedescription is updated to "shared" to be compatible with HEAD.Per discussion with Nazir Bilal Yavuz and Hubert Depesz Lubaczewski,whose EXPLAIN analyzer tool was not actually able to parse the previousterm because of the slash character.Discussion:https://postgr.es/m/ZTCTiUqm_H3iBihl@paquier.xyzBackpatch-through: 15
