Summary: 'null' from copy into gets wrong
Initial Comment:
There are two issues here; one is easy to reproduce the other one I cannot yet
reproduce in a smaller setting.
Create a file /tmp/nullcheck containing:
'null'
create table testnull (test varchar(10));
copy 1 records into testnull from '/tmp/nullcheck' USING DELIMITERS '\n', '''';
select * from testnull will give now an empty value.
While: insert into testnull values('null'); will result into the string 'null'
inside the table.
The actual observation was that anything starting with 'nu...' would become a
null variable; but outside the OSM insert script I cannot reproduce this
behavior. The expected behavior would be that 'null' would be just the string.
While the quoteless variant would get into NULL.

Message:
Other (worse) example now works too:
CREATE TABLE "sys"."node_tags" (
"node" int,
"k" varchar(255),
"v" varchar(1024)
);
/tmp/nulltest:
1, 'test', 'Nullen RA'
COPY 1 RECORDS INTO node_tags from '/tmp/nulltest' USING DELIMITERS ',',
'\n', '''';
sql>select * from node_tags;

| node | k | v |

| 1 | test | n |
