TITLE: Allow parenthesized query expression for standard-compliance TITLE: Allow parenthesized query expression for standard-compliance
DESCRIPTION: DESCRIPTION:
NOTES: Queries which do not use `WITH` clause now can be enclosed in parenthesis,
Queries which do not use `WITH` clause now can be enclosed in parenthesis, but this leads to reduced number of max parts of UNIONed query, from 255 to 128.
but this leads to reduced number of max parts of UNIONed query, from 255 to 128.

NOTES:
[30.06.2022] pzotov
Error message in case when NUM_OF_UNIONED_PARTS >= 129 can obfuscate:
"Too many Contexts of Relation/Procedure/Views. Maximum allowed is 256"
Max limit of unioned-parts is 128, it was explained by Adriano in the ticket.
Checked on 5.0.0.509.
