You want to create variable table or function names in postgresql
In the case of executing dynamic sql commands, you can use the execute command in pl/pgsql.
CREATE FUNCTION somefunction(name varchar, language varchar)
RETURNS void AS
table_cmd; --the command that we build to execute
tablename := $1 || 'suffix'; --naming convention
table_cmd := 'create table ' || tablename
|| ' ( ' || primkey || ' serial unique,'
|| 'Title varchar(255) not null,'
|| 'Symptom varchar(1500) not null,'
|| 'Cause varchar(1500) default ''the'');'
raise notice 'table_cmd is %', table_cmd; --show some information when run
--EXECUTE table_cmd; --comment this out to create the table
LANGUAGE 'plpgsql' VOLATILE;
