Autopartitioning Postgresql for Zabbix - postgresql

Question

The goal, аutopartitioning for 7 days. And after 14 days to delete the old partitions. In this example, everything works. But, when I try to write data of the form :
insert into history_str (itemid, clock, ns, value) values (40,151,3722, '3.0.3');
I get an error
ERROR: syntax error at or near ".3"
LINE 1: ... istory_str_2018_02_07 values (40,151,3.0.3,3722 ...
                                                    ^
QUERY: INSERT INTO history_str_2018_02_07 values (40,151,3.0.3,3722);
CONTEXT: PL / pgSQL function create_partition_other () line 37 at EXECUTE
Here is the actual code example
CREATE OR REPLACE FUNCTION create_partition() RETURNS trigger AS
$BODY$
DECLARE
partition_name TEXT;
partition_week TEXT;
partitions_names TEXT;
date_search TEXT;
sql_search TEXT;
var_data TEXT;
typeof BOOL;
BEGIN
partition_week := to_char(to_timestamp(NEW.clock),'IW');
RAISE INFO 'Week now: %',partition_week;
partition_name := TG_TABLE_NAME || '_' || to_char(to_timestamp(NEW.clock),'YYYY_MM') || '_' || partition_week;
RAISE INFO 'Master Table: %',TG_TABLE_NAME;
RAISE INFO 'Partit. name: %',partition_name;
IF NOT EXISTS(SELECT relname FROM pg_class WHERE relname = partition_name) THEN
RAISE INFO 'Create table';
EXECUTE 'CREATE TABLE ' || partition_name || ' (check (clock >= ' || quote_literal(NEW.clock) || ' AND clock < ' || quote_literal(NEW.clock + integer '7' * integer '86400') || ')) INHERITS (' || TG_TABLE_NAME || ');';
EXECUTE 'INSERT INTO create_tables_date (name,date) values (' || quote_literal(partition_name) || ',' || quote_literal(to_timestamp(NEW.clock)) || ');';
date_search := quote_literal(date (to_char(to_timestamp(NEW.clock),'YYYY_MM_DD'))-integer '7');
RAISE INFO 'Search data: %',date_search;
sql_search := 'SELECT name FROM create_tables_date WHERE date < ' || date_search || ';';
for partitions_names in EXECUTE sql_search LOOP
IF partitions_names IS NOT NULL THEN
RAISE INFO 'DROP, DELETE: %',partitions_names;
EXECUTE 'DROP TABLE ' || partitions_names || ';';
EXECUTE 'DELETE FROM create_tables_date WHERE name=' || quote_literal(partitions_names) || ';';
END IF;
END LOOP;
END IF;
RAISE INFO 'Value: %',NEW.value;
var_data := 'INSERT INTO ' || partition_name || ' values ' || NEW || ';';
RAISE INFO 'SQL: %',var_data;
EXECUTE var_data;
RETURN NULL;
END;
$BODY$
LANGUAGE plpgsql VOLATILE
COST 100;
I found out that the problem when writing the values of being in NEW.value.And after replacing the characters [(), \] with _, the problem was solved.
That is, I redefine before an insert NEW.value
NEW.value := quote_literal(regexp_replace(NEW.value,'[(),\ ]','_','g'));
But this is the case if I try to write to a table with a column value, and if there is no other table, I have to write many identical functions for each table. What is bad.
Can you know why this situation arises with these symbols?

You could try USING and expand row with asterisk:
var_data := 'INSERT INTO ' || partition_name || ' values ($1.*);';
RAISE INFO 'SQL: %',var_data;
EXECUTE var_data using new;
