Postgres relationships fail to import when ONLY keyword is present in ALTER TABLE statements

[alexemitwise]

Describe the bug
When the ONLY keyword is present in ALTER TABLE statements (generated by pg_dump) the foreign key relationships fail to import.

My workaround for the minute is to simply delete all occurrences of the ONLY keyword, so should be fine to add the same step in parser.

Obvious fix once you know but subtle enough to put a lot of people off from using the tool.

To Reproduce
Steps to reproduce the behavior:

1. Import the following schema sql:

CREATE TABLE foo (
 a int,
)

CREATE TABLE bar (
 b int,
)

ALTER TABLE ONLY foo
ADD CONSTRAINT foo_bar_fkey
FOREIGN KEY (a) REFERENCES bar(b)

ALTER TABLE ONLY bar
ADD CONSTRAINT bar_foo_fkey
FOREIGN KEY (b) REFERENCES foo(a)

Expected behavior
Relationships to be present.
