Hi Pavel, I have reviewed the patch and here are my concerns and notes:
POSITIVES: --- 1. Patch applies with some white-space errors. 2. make / make install / make check is smooth. No issues as such. 3. Feature looks good as well. 4. NO concern on overall design. 5. Good work. NEGATIVES: --- Here are the points which I see in the review and would like you to have your attention. 1. + It use conditional commands (with <literal>IF EXISTS</literal> Grammar mistakes. use => uses 2. @@ -55,7 +55,8 @@ static ArchiveHandle *_allocAH(const char *FileSpec, const ArchiveFormat fmt, const int compression, ArchiveMode mode, SetupWorkerPtr setupWorkerPtr); static void _getObjectDescription(PQExpBuffer buf, TocEntry *te, ArchiveHandle *AH); -static void _printTocEntry(ArchiveHandle *AH, TocEntry *te, RestoreOptions *ropt, bool isData, bool acl_pass); +static void _printTocEntry(ArchiveHandle *AH, TocEntry *te, RestoreOptions *ropt, + bool isData, bool acl_pass); static char *replace_line_endings(const char *str); static void _doSetFixedOutputState(ArchiveHandle *AH); static void _doSetSessionAuth(ArchiveHandle *AH, const char *user); @@ -234,6 +235,7 @@ RestoreArchive(Archive *AHX) bool parallel_mode; TocEntry *te; OutputContext sav; + AH->stage = STAGE_INITIALIZING; @@ -2961,7 +3005,8 @@ _getObjectDescription(PQExpBuffer buf, TocEntry *te, ArchiveHandle *AH) } static void -_printTocEntry(ArchiveHandle *AH, TocEntry *te, RestoreOptions *ropt, bool isData, bool acl_pass) +_printTocEntry(ArchiveHandle *AH, TocEntry *te, RestoreOptions *ropt, bool isData, + bool acl_pass) { /* ACLs are dumped only during acl pass */ if (acl_pass) Above changes are NOT at all related to the patch. Please remove them even though they are clean-up like changes. Don't mix them with actual changes. 3. + if (strncmp(te->dropStmt + desc_len + 5, " IF EXISTS", 9) != 0) " IF EXISTS" has 10 characters NOT 9. 4. + if (strncmp(te->dropStmt + desc_len + 5, " IF EXISTS", 9) != 0) + ahprintf(AH, "DROP %s IF EXISTS %s", + te->desc, + te->dropStmt + 6 + desc_len); Here you have used strncmp, starting at te->dropStmt + X, where X = desc_len + 5. While adding back you used X = 6 + desc_len. First time you used 5 as you added space in comparison but for adding back we want past space location and thus you have used 6. That's correct, but little bit confusing. Why not you simply used + if (strstr(te->dropStmt, "IF EXISTS") != NULL) to check whether drop statement has "IF EXISTS" or not like you did at some other place. This will remove my concern 3 and above confusion as well. What you think ? 5. + } + + else Extra line before else part. Please remove it for consistency. 6. + printf(_(" --if-exists use IF EXISTS when dropping objects\n")); (pg_dump) + printf(_(" --if-exists don't report error if cleaned object doesn't exist\n")); (pg_dumpall) + printf(_(" --if-exists use IF EXISTS when dropping objects\n")); (pg_restore) Please have same message for all three. 7. printf(_(" --binary-upgrade for use by upgrade utilities only\n")); printf(_(" --column-inserts dump data as INSERT commands with column names\n")); + printf(_(" --if-exists don't report error if cleaned object doesn't exist\n")); printf(_(" --disable-dollar-quoting disable dollar quoting, use SQL standard quoting\n")); printf(_(" --disable-triggers disable triggers during data-only restore\n")); Please maintain order like pg_dump and pg_restore. Also at variable declaration and at options parsing mechanism. 8. + if (if_exists && !outputClean) + exit_horribly(NULL, "option --if-exists requires -c/--clean option\n"); Are we really want to exit when -c is not provided ? Can't we simply ignore --if-exists in that case (or with emitting a warning) ? Marking "Waiting on author".
