From 7f14bf122427a30f62e98ad65d4856455578cfc3 Mon Sep 17 00:00:00 2001 From: Fujii Masao Date: Wed, 9 Apr 2025 18:21:18 +0900 Subject: [PATCH v2] psql: Improve tab completion for COPY command. Previously, tab completion for COPY only suggested plain tables and partitioned tables, even though materialized views are also valid for COPY TO (since commit 534874fac0b), and foreign tables are valid for COPY FROM. This commit enhances tab completion for COPY to also include materialized views and foreign tables. Views with INSTEAD OF INSERT triggers are supported with COPY FROM but rarely used, so plain views are intentionally excluded from completion. --- src/bin/psql/tab-complete.in.c | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) diff --git a/src/bin/psql/tab-complete.in.c b/src/bin/psql/tab-complete.in.c index c916b9299a8..9846b086ef2 100644 --- a/src/bin/psql/tab-complete.in.c +++ b/src/bin/psql/tab-complete.in.c @@ -889,6 +889,14 @@ static const SchemaQuery Query_for_list_of_analyzables = { .result = "c.relname", }; +/* + * Relations supporting COPY TO/FROM are currently almost the same as + * those supporting ANALYZE.
