In copydir.c:copy_file() I read
/* Use palloc to ensure we get a maxaligned buffer */
buffer = palloc(COPY_BUF_SIZE);No data type wider than a single byte is used to access the data in the buffer, and neither read() nor write() should require any specific alignment. Can someone please explain why alignment matters here? -- Antonin Houska Web: https://www.cybertec-postgresql.com
