Description OSIDB Bzimport 2026-08-13 13:27:33 UTC 
Buffer over-read in PostgreSQL pg_trgm index picksplit function reads past end of a heap buffer.  This might allow a table maintainer to infer limited memory values, via the lossy signal of index split choices.  Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.
