Actually, the error occurred without the "Array-containselem-gin-v1.patch".
However, I also had the
"v3-0001-Add-primary-keys-and-unique-constraints-to-system.patch", to get PKs
on the oids.
So, I've retested to ensure it didn't cause this problem,
this time only 7e57255f6189380d545e1df6a6b38827b213e3da +
"Array-ELEMENT-foreign-key-v13.patch",
but I still get the same error though.
Exact steps to reproduce error from a clean installation:
$ cd postgresql
$ git checkout 7e57255f6189380d545e1df6a6b38827b213e3da
$ patch -p1 < ~/Array-ELEMENT-foreign-key-v13.patch
$ ./configure --prefix=~/pg-head
$ make -j16
$ make install
$ initdb -D ~/pghead
$ pg_ctl -D ~/pghead -l /tmp/logfile start
$ createdb $USER
$ psql
CREATE SCHEMA catalog_clone;
CREATE TABLE catalog_clone.pg_proc AS SELECT * FROM pg_catalog.pg_proc;
CREATE TABLE catalog_clone.pg_type AS SELECT * FROM pg_catalog.pg_type;
ALTER TABLE catalog_clone.pg_type ADD PRIMARY KEY (oid);
ALTER TABLE catalog_clone.pg_proc ADD FOREIGN KEY (EACH ELEMENT OF proargtypes)
REFERENCES catalog_clone.pg_type (oid);
UPDATE catalog_clone.pg_proc SET proargtypes = '19 25 12345'::oidvector WHERE
oid = 79;
