On 0002:
+ This option can only be used in conjunction with
+ <option>--analyze-only</option> and
<option>--analyze-in-stages</option>.
+ /* Prohibit --missing-only without --analyze-only or --analyze-in-stages */
+ if (vacopts.missing_only && !vacopts.analyze_only)
+ pg_fatal("cannot use the \"%s\" option without \"%s\" or \"%s\"",
+ "missing-only", "analyze-only", "analyze-in-stages");
The first is slightly ambiguous, so maybe "or" is better throughout.
+ " CROSS JOIN LATERAL (SELECT c.relkind IN ('p', 'I')) as p (inherited)\n"
Looking elsewhere in this file, I think we prefer something like
"(c.relkind OPERATOR(pg_catalog.=) ANY (array["
CppAsString2(RELKIND_PARTITIONED_TABLE) ", "
CppAsString2(RELKIND_PARTITIONED_INDEX) "]) as p (inherited)\n"
+ " AND NOT EXISTS (SELECT NULL FROM pg_catalog.pg_statistic s\n"
+ " WHERE s.starelid OPERATOR(pg_catalog.=) a.attrelid\n"
+ " AND s.staattnum OPERATOR(pg_catalog.=) a.attnum\n"
+ " AND s.stainherit OPERATOR(pg_catalog.=) p.inherited))\n");
IIUC correctly, pg_statistic doesn't store stats on itself, so this
causes the query result to always contain pg_statistic -- does that
get removed elsewhere?
