some issues with sogo 5.7.1 in 7.2

Hi,

finally upgraded my work sogo instance, hit two distinct issues
unrelated to the WOPort one, both seen when trying to login:

[GCSSessionsFolder
writeRecordForEntryWithID:value:creationDate:lastSeenDate:]: cannot
write record: <PostgreSQL72Exception: 0x313372437c8>
NAME:PostgreSQL72FatalError REASON:fatal pgsql error
(channel=<0x0x31374da1608[PostgreSQL72Channel]:
connection=<0x0x3135d728468[PGConnection]:
connection=0x0x313651c3800>>): ERROR: value too long for type character
varying(255)

found https://bugs.sogo.nu/view.php?id=5491 - from what i can see,
https://github.com/Alinto/sogo/blob/master/Scripts/sql-update-5.5.1_to_5.6.0.sh
isnt packaged in /usr/local/share/doc/sogo/. Maybe the PLIST should be
updated ? anyway, solved it locally with psql:

sogo=> ALTER TABLE sogo_sessions_folder ALTER COLUMN c_value TYPE
VARCHAR(4096);

but also 'upstream sent too big header while reading response header
from upstream' in nginx error logs, cf
https://www.sogo.nu/support/faq/errors-in-nginx-regarding-header-too-big.html#/faq

i already had some proxy buffers config in nginx (coming from the
pkg-readme), had to bump them and could login just fine.

so .. maybe also update the pkg-readme with the values recommended
upstream ?
