From 438fe2650181ce34e66968b4667dff7ba90663cb Mon Sep 17 00:00:00 2001 From: Atsushi Torikoshi Date: Wed, 2 Jul 2025 14:26:32 +0900 Subject: [PATCH v3 2/2] Improve tab completion for COPY options Currently, COPY FROM and TO share the same tab completion rules, even though some options are only valid for one or the other. This patch separates the tab completion rules for COPY FROM and COPY TO to provide more accurate suggestions. --- src/bin/psql/tab-complete.c | 24 +++++++++++++++++++----- 1 file changed, 19 insertions(+), 5 deletions(-) diff --git a/src/bin/psql/tab-complete.c b/src/bin/psql/tab-complete.c index 5b909d6f3a0..7e36cb11973 100644 --- a/src/bin/psql/tab-complete.c +++ b/src/bin/psql/tab-complete.c @@ -1022,6 +1022,18 @@ static const SchemaQuery Query_for_list_of_collations = { " FROM pg_catalog.pg_cursors "\ " WHERE substring(pg_catalog.quote_ident(name),1,%d)='%s'" +/* COPY options shared between FROM and TO */ +#define Copy_common_options \ +"DELIMITER", "ENCODING", "ESCAPE", "FORMAT", "HEADER", "NULL", "QUOTE" + +/* COPY FROM options */ +#define Copy_from_options \ +Copy_common_options, "FORCE_NOT_NULL", "FORCE_NULL", "FREEZE" + +/* COPY TO options */ +#define Copy_to_options \ +Copy_common_options, "FORCE_QUOTE" + /* * These object types were introduced later than our support cutoff of * server version 7.4.
