[HACKERS] Parser extensions (maybe for 10?)
I thought I'd float this idea and see if this gets any traction. Please
forgive my ignorance if this has been discussed already.
Currently the parser and lexer are fully fixed at compile-time and not
amenable to the extensions - extensions are only capable of introducing
functions etc.
There is, however, an advantage to being able if not add or alter
complete statements (which would be nice), but to at least augment
portions of syntax for existing ones in some places.
For example PGXL adds the following to CREATE TABLE statement:
[
DISTRIBUTE BY { REPLICATION | ROUNDROBIN | { [HASH | MODULO ] (
column_name ) } } |
DISTRIBUTED { { BY ( column_name ) } | { RANDOMLY } |
DISTSTYLE { EVEN | KEY | ALL } DISTKEY ( column_name )
]
[ TO { GROUP groupname | NODE ( nodename [, ... ] ) } ]
Compare:
http://www.postgresql.org/docs/9.5/static/sql-createtable.html
http://files.postgres-xl.org/documentation/sql-createtable.html
Is there any interest and/or tips to allow a pluggable parser or at
least allow some syntactical pluggability by extensions?
I think this may allow some projects to move towards becoming an
extension as opposed to forking the project entirely.
Cheers,

Re: [HACKERS] Corporate and Individual Contributor License Agreements (CLAs)
Thank you Magnus. The absence of legal entity and therefore of CLAs will make for an awesome discussion with legal. :D On 2014-10-06 16:04, Magnus Hagander wrote: On Mon, Oct 6, 2014 at 9:58 PM, Arcadiy Ivanov arca...@gmail.com wrote: Hi folks, My corp (CSC) OSS division requires CLAs to be signed for OSS project participation to begin.

There are no such agreements for Postgres work. The community explicitly rejected the idea more than a dozen years ago. If your lawyers can't cope with the concept of informal communities, I'm sorry, but we're not going to burden ourselves with paperwork in order to make them happy. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
