Hello, I’m running 9.4.5 locally on my mac doing some plpgsql development.
Here is a simplified version of the function:
CREATE OR REPLACE FUNCTION create_table(
new_table_schema character varying,
new_table_name character varying,
create_log boolean DEFAULT true,
create_source boolean DEFAULT false
) RETURNS void AS
$BODY$
declare
the_tables text[][];
the_table text[];
begin
-- Generate array of tables to create
the_tables[1] := array[new_table_schema, new_table_name];
if (create_source) then
the_tables[2] := array[new_table_schema||'_source', new_table_name||'_source'];
end if;
RAISE NOTICE 'the_tables = %', the_tables;
<<BIGLOOP>>
foreach the_table slice 1 in array the_tables
loop
raise notice 'schema = %; table = %', the_table[1], the_table[2];
end loop BIGLOOP;
end;
$BODY$
LANGUAGE plpgsql;
When I run it, I get the following message output:
NOTICE: the_tables = {"{mike,test}","{mike_source,test_source}"}
NOTICE: schema = {mike,test}; table = {mike_source,test_source}
I am expecting:
NOTICE: the_tables = {{'mike','test'},{'mike_source','test_source'}}
NOTICE: schema = mike; table = test
NOTICE: schema = mike_source; table = test_source
I suspect something is happening with the assignment operator :=, as those double quotes seem to indicate the subarrays are being cast to strings?
I tried casting during the assignment, i.e. the_tables[1] := array[new_table_schema, new_table_name]::text[], but that had no effect.
Does anyone know what I might be doing wrong?
