Yes, I will implement regression test patch and documentation patch as well.
Attached latest version patch supporting s_s_names = '*'.
Unlike currently behaviour a bit, s_s_names can have only one '*' character.
e.g, The following setting will get syntax error.
s_s_names = '*, node1,node2'
s_s_names = `2[node1, *, node2]`
when we use '*' character as s_s_names element, we must set s_s_names
like follows.
s_s_names = '*'
s_s_names = '2[*]'
BTW, we've discussed about mini language syntax.
IIRC, the syntax uses [] and () like,
'N[node1, node2, ...]', to define priority standbys.
'N(node1, node2, ...)', to define quorum standbys.
And current patch behaves so.
Which type of parentheses should be used for this syntax to be more clarity?
Or other character should be used such as <>, // ?
