Indexes not created properly when using COPY

[daviesluke]

Example 1

Table created as `CREATE TABLE test1 ( id VARCHAR2(20) NOT NULL, desc VARCHAR2(20) );

CREATE INDEX test1_idx ON test1 ( TO_NUMBER(ID) );`

When running in TABLE mode get the following SQL generated CREATE INDEX test1_idx ON test1 (((nullif(id, '')::numeric)));

When running in COPY mode get the following SQL generated CREATE INDEX test1_idx ON test1 ((id)::numeric);

2nd SQL is invalid.

Example 2

Table created as `CREATE TABLE test2 ( id VARCHAR2(254) NOT NULL, config_path VARCHAR2(254) NOT NULL, start_time TIMESTAMP(6) NOT NULL );

CREATE INDEX test2_idx ON test2 ( config_path, start_time desc );`

When running in TABLE mode get the following SQL generated CREATE INDEX test2_idx ON test2 (config_path, start_time desc);

When running in COPY mode get the following SQL generated CREATE INDEX test2_idx ON test2 (config_path, ("start_time desc"));

2nd SQL is invalid
