I removed it in 0002 since the final commit would indeed not be so indented. The tag itself doesn't actually care but its content does indeed get undesirably indented if the markup is nested in the typical manner.

i didn't apply patch 0002, 0001 is already too much.

attached image.png for
5.2.7.2. Array Elements and IN Bag Members
the example is too overwhelming, one or two should be enough?

5.2.7.3. Single-Column Subquery Rows.
two examples, can be reduced to one.

typo:
There are none. During initializion all settings are assigned a non-null value.
5.2.16. Null Values in Partiton Keys
As noted in the synatx chapter, a null value literal is written using
the NULL keyword. Its type is the pseudo-type unknown but can be cast
to any concrete data type.

""
At present this is typically a non-issue as PostgreSQL does not
support a primary key that does not include partition key columns, and
all columns in a primary key are forced to be have not null
constraints.
""
"does not support...does not include" double negation, can we make it
"positive".
"not null constraints." should be "not-null constraints"?
