Neighbor uses salt water on his pavers 2x a year and seems to have the weeds

Interesting idea, as long as you don't have salt water tolerant weeds.

I am looking into doing my yard with Seashore Paspalum grass. My
wife's golf course experimented with it and it was OK there but the
old timer "grass boys" resisted it.

The advantage for me is I could irrigate with tide water and to the
best of my knowledge that is not subject to watering restrictions.
It would be an interesting case if they tried to get me.

Would that make your yard smell like...low tide? :)

Pouring salt on pavers is not a terrific idea. While the typical
efflorescence problems that sometimes occur with brick are based upon
salt leeching out of masonry units and settling on their surface, the
white stuff can also occur because of salt poured on the units and the
water carrying them evaporating. Also, as you know brick are porous, so
the salt can get inside them...and then leech out. There's also a
problem pouring salt on concrete products...it's called secondary
efflorescence.

Boy, that spoofer sure knows how to google, eh? You do realize, spoofer,
that there are many, many reasons for efflorescence don't you? And to
address your google cut and paste, there are three things that must
occur to cause a cementitious unit to show signs of efflorescence. One
of those is simply the presence of ALKALI salts. Secondly, enough
moisture to render the salts into a soluble solution. Then, a path to
the surface. Washing pavers once in awhile with salt water will NOT soak
the units enough to do this.
